Description Liangent 2013-06-30 12:21:37 UTC 
The reason that no RegEx support is added in Lua by default is to reduce the total size of Lua runtime. However as we're running Lua on servers now, size is not something critical for us.

On the other hand, it's very easy to create pathological regular expressions. This is much less likely with Lua patterns, and we were able to easily add checkpoints into Lua's pattern processing to allow Scribunto's CPU limiting to continue to work even if someone does manage this. Doing the same for a regex engine is likely to be more difficult.

I don't think this is going to happen.
