The exclamation marks are used to indicate the beginning and the end of the
pattern. The following will also work:

#(pattern)#
|(pattern)|
?(pattern)?

.....or any character that's not in use by the pattern. This is not a
restriction, however, because you can escape characters with a backslash
when they occur both in the pattern and as pattern delimiters:

|(a\|b)|
