Update the regexp to conditionally (naively?) change the current start,end delimiters for the regexp from the hard-coded '<','>' to '{','}' when the compiler encounters a pattern that has syntax that includes '(?<' or '(?>' organically.

Thank you for the changes, however the reason lookbehind is not working is because we're using the golang std library, which does not support these features.
