{AST} is a library for manipulating abstract syntax trees.
It embraces immutability; each AST node is inherently frozen at creation, and updating a child node requires recreating that node and its every parent, recursively.
This is a design choice. It does create some pressure on garbage collector, but completely eliminates all concurrency and aliasing problems.
See also {AST::Node}, {AST::Processor::Mixin} and {AST::Sexp} for additional recommendations and design patterns.
