No, perl seems to be able to parse the inner "[]" correctly even with the same characters as outer delimiters. The real problem with the original pattern is that "." is not a metacharacter inside character classes. The given class matched only real "."s and newlines. That's why I suggested the "s" option.

According to Mastering Regular Expressions, p. 10:

...to be clear, the only special characters within the class in [0-9A-Z_!.?] are the two dashes.
