First of all, I'd like to express my gratitude and appreciation for Nim — I've been following the project since Nim v0.10 (more or less), although I've never managed to find enough time to dedicate myself to study the language and experiment with it as I should have (I even bought a very early MEAP of the excellent "Nim in Action" book).
Finally, I'm now able to dedicate myself to learning Nim on an almost daily basis, and I'm starting to port to Nim some prototype projects which I had created with some quick-to-use languages, but now deserve to be reimplemented in a solid language. I'm really impressed by the philosophy behind Nim, and the clean syntax it offers. I hope I'll be able to contribute to the project in the course of time. Right now, I'm porting a project which relies on RegExs (the original code uses PCRE). After having looked at the impure **re** library and the **pcre** wrapper, as well as the **nre** library, and having compared them to the **strscans** library, I'm tempted to use the latter for my project, for it seems to cover all the pattern needs of my code (not complex patterns, but quite a lot of them). I like **strscans** because it's extensible, and simpler to use than any of the current PCRE solutions, and most of all is in pure Nim and doesn't require third party dependencies. I have a few questions though... Performance wise, how does **strscans** compare to PCRE based libraries? My project has to perform a huge quantity of pattern matching, so performance might be a concern if the difference is huge. Overall, I'd like to prioritize code usability over performance right now, but being a CLI tool that is used to process many input text files, I can't afford a significant degrade in performance, but I it's OK if the difference is marginal. Also, I wanted to ask about the **nre** library status. I've looked at its documentation and the GitHub issues linked therein, and learned that it's now part of the Nim Standard Library, but couldn't really work out its current status. What I don't understand is: why it's not linked in the documentation page for the StdLib? and why it resides in a subfolder of its own (`lib\impure\nre\private\`)? Thanks
