Thanks. Looks kind of complicated. Are there any examples of how to use this stuff?

Hi Michael

I think you want to be using a one of the 'implementation' packages
directly rather than Text.Regex.Base.RegexLike (from regex-base), for
instance regex-posix. If you are searching a string you would want to
import the Text.Regex.Posix.String module.

Text.Regex.Base.RegexLike provides the interface, specific matchers
(e.g. Posix or PCRE) provide the implementation.

Best wishes
