#### Using Acorn in an environment with a Content Security Policy
Some contexts, such as Chrome Web Apps, disallow run-time code evaluation.
Acorn uses `new Function` to generate fast functions that test whether
a word is in a given set, and will trigger a security error when used
in a context with such a
[Content Security Policy](http://www.html5rocks.com/en/tutorials/security/content-security-policy/#eval-too)
(see [#90](https://github.com/marijnh/acorn/issues/90) and
[#123](https://github.com/marijnh/acorn/issues/123)).
The `dist/acorn_csp.js` file in the distribution (which is built
by the `bin/without_eval` script) has the generated code inlined, and
can thus run without evaluating anything.
