Title: Pattern failure
Name: Hardryv

Comment:
parsing "^(?!00000)(?\d{5})(?:(?:[- ]?)(?\d{4}))?$" - Unrecognized grouping construct
I had high hopes that this pattern would not only lead me to a solution, but also teach me something. For some reason it failed when tested. Can you please fix it or advise me what switches you ran it with to test it please?
