Summary
Using a dedicated package I created for transparently creating regular expressions with the
lflag (when available). This requires some refactoring to avoid significant performance overhead by pre-initializing the regular expressions in a closure which can than reuse it for repeated escaping.For this proof of concept I just implemented it for one of the escape modules. Also, it is not tested yet as I did not figure out a way to run AVA tests with the
--enable-experimental-regexp-engineflag.
