The problem is that the exclamation point is not a word character, so 
there is no word boundary after the character, i.e. the pattern should 
be:
    match = "\\<(action!|any-block!|any-function!)"

If you want to guard against word-characters _after_ the exclamation 
point, you could do:
    match = "\\<(action!|any-block!|any-function!)(?!\w)"

But I think only the word-begin-boundary really matters in your case.


Kind regards Allan
