# New Ticket Created by l.mai [at] web

This is a bug report for perl from l.mai [at] web,
generated with the help of perlbug 1.39 running under perl 5.16.0.
-----------------------------------------------------------------
[Please describe your issue here]
All of these should warn about illegal prototypes but don't:
% perl -we 'sub f ([)'
% perl -we 'sub f (][.[.[.[.[.[.)'
% perl -we 'sub f (\;)'
% perl -we 'sub f (\[_;@])'
% perl -we 'sub f (\+)'
% perl -we 'sub f (\\\\)'
% perl -we 'sub f ([$])'
This one warns for the wrong reason:
% perl -we 'sub f (\[_$])'
Illegal character after '_' in prototype for main::f : \\[_$] at -e line 1.
This one is semantically nonsense but "works":
% perl -we 'sub f (_;_;_)'
[Please do not change anything below this line]
