- `join_vars` (default: `true`) -- join consecutive `var` statements
- `keep_fargs` (default: `strict`) -- Discard unused function arguments. Code
which relies on `Function.length` will break if this is done indiscriminately,
i.e. when passing `true`. Pass `false` to always retain function arguments.
- `keep_fargs` (default: `false`) -- discard unused function arguments except
when unsafe to do so, e.g. code which relies on `Function.prototype.length`.
Pass `true` to always retain function arguments.

compressor from discarding function names. Useful for code relying on
