       Because many operating systems silently chop off kernel
       interpretation of the #! line after 32 characters, some
       switches may be passed in on the command line, and some
       may not; you could even get a "-" without its letter, if
       you're not careful.  You probably want to make sure that
       all your switches fall either before or after that 32
       character boundary.  Most switches don't actually care if
       they're processed redundantly, but getting a - instead of
       a complete switch could cause Perl to try to execute
       standard input instead of your script.  And a partial -I
       switch could also cause odd results.
