make sure we don't choke on specific input\n *\n *  - since JavaScript has no possessive quantifier or atomic grouping\n *    we are emulating it with a trick\n *\n *    we want a possessive quantifier or atomic group to prevent backtracking\n *    on the `}`s should we fail to match the remainder of the pattern\n *\n *    we can emulate this with a positive lookahead and back reference\n *    (a++)*c === ((?=(a+))\\1)*c\n *\n *    let's examine an example:\n *      - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps\n *      - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps\n *      - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps\n *\n *    this is because the possessive `++` and the atomic group `(?>)`\n *    tell the engine that all those `a`s belong together as a single group\n *    and so it won't split it up when stepping backwards to try and match\n *\n *    if we use /((?=(a+))\\1)*c/ then we get the same behavior as the atomic group\n *    or possessive and prevent the backtracking because the `a+` is matched but\n *    not captured. thus, we find the long string of `a`s and remember it, then\n *    reference it as a whole unit inside our pattern\n *\n *    @cite http://instanceof.me/post/52245507631/regex-emulate-atomic-grouping-with-lookahead\n *    @cite http://blog.stevenlevithan.com/archives/mimic-atomic-groups\n *    @cite

make sure we don't choke on specific input\n *\n *  - since JavaScript has no possessive quantifier or atomic grouping\n *    we are emulating it with a trick\n *\n *    we want a possessive quantifier or atomic group to prevent backtracking\n *    on the `}`s should we fail to match the remainder of the pattern\n *\n *    we can emulate this with a positive lookahead and back reference\n *    (a++)*c === ((?=(a+))\\1)*c\n *\n *    let's examine an example:\n *      - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps\n *      - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps\n *      - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps\n *\n *    this is because the possessive `++` and the atomic group `(?>)`\n *    tell the engine that all those `a`s belong together as a single group\n *    and so it won't split it up when stepping backwards to try and match\n *\n *    if we use /((?=(a+))\\1)*c/ then we get the same behavior as the atomic group\n *    or possessive and prevent the backtracking because the `a+` is matched but\n *    not captured. thus, we find the long string of `a`s and remember it, then\n *    reference it as a whole unit inside our pattern\n *\n *    @cite http://instanceof.me/post/52245507631/regex-emulate-atomic-grouping-with-lookahead\n *    @cite http://blog.stevenlevithan.com/archives/mimic-atomic-groups\n *    @cite

make sure we don't choke on specific input\n *\n *  - since JavaScript has no possessive quantifier or atomic grouping\n *    we are emulating it with a trick\n *\n *    we want a possessive quantifier or atomic group to prevent backtracking\n *    on the `}`s should we fail to match the remainder of the pattern\n *\n *    we can emulate this with a positive lookahead and back reference\n *    (a++)*c === ((?=(a+))\\1)*c\n *\n *    let's examine an example:\n *      - /(a+)*c/.test('aaaaaaaaaaaaad') fails after over 49,000 steps\n *      - /(a++)*c/.test('aaaaaaaaaaaaad') fails after 85 steps\n *      - /(?>a+)*c/.test('aaaaaaaaaaaaad') fails after 126 steps\n *\n *    this is because the possessive `++` and the atomic group `(?>)`\n *    tell the engine that all those `a`s belong together as a single group\n *    and so it won't split it up when stepping backwards to try and match\n *\n *    if we use /((?=(a+))\\1)*c/ then we get the same behavior as the atomic group\n *

- - We only have one or two distinct tokens, depending on how you look at it, and they are all readily matched via a regular expression.

The parser generated by the PEG provides predictable performance characteristics in exchange for control over tokenization rules -- it doesn't allow us to define RegExp patterns in the rules so as to guard against _e.g._ cataclysmic backtracking that would break the PEG guarantees.
