[Haskell-cafe] How does one use Text.Regex.Base.RegexLike?

[Lyle Kopnicky]

Yes, that worked, thanks. I just figured that out too. Here's a whole
working program:

import Text.Regex.Base
import Text.Regex.Posix

rx :: Regex
rx = makeRegex "a(.*)A"

mr = match rx "abcdA"

text = head $ mrSubList mr

main = putStrLn text
