Compiles a regular expression


re = rex.new (pattern, flags)


This compiles a pattern, returning a regular expression object that can be used to test regular expressions. For example:

re = rex.new ("(.+) goes (.+)")

Flags are optional. If you want to use them you can use the rex.flags () function to convert various flags into numbers.
