A string literal like "-I" confuses the parser.

perl-wtf-1

Without the leading "-" as the first character within it, it's fine.

perl-wtf-2
perl-wtf-3

Of course, since it accepts "-D..." first, the answer isn't quite that simple. It seems more subtle even, because if I simply insert a linefeed after the comma then it parses fine:

perl-wtf-4

Actually it seems that a leading "+" symbol can confuse it too. I really now have no idea what's going on:

perl-wtf-5
