in reply to Hash key/value

FireBird34: As mentioned above, you don't say how  ' and  ! fail to behave as you 'expect'! Can you give some examples?

Remember, the strings in your OP are single-quoted strings, and the  \ (backslash) has very limited function when used as an escape in a single-quoted string. In essence,  \ only escapes itself and  ' in such a string.

See the discussion of  '' and  q{} in the Quote and Quote like Operators section (and in Quote Like Operators) of perlop.

    For example, 

    print 'that\'s it',    "\n";
print 'that\'s it\!',  "\n";
print 'that\'s it\\!', "\n";

    that's it         \ escapes the delimiter (')
that's it\!       \ wasn't followed by the delimiter (') or \
that's it\!       \ escapes \

    Contrast with double-quotes: 

    print "\"that's it!\"\n";
print "\"that's it\!\"\n";
print "\"that's it\\!\"\n";

    [download]
    "that's it!"      \ escapes "
"that's it!"      \ escapes !
"that's it\!"     \ escapes \

    Problem was resolved. Problem turned out to be me. I didn't properly take into account the extra '. Stupid mistake :) Thank you for the help.
