[ID 20000128.001] $a = 1,,,,,,,,,

[Michael Cook <cook@sightpath.com>]

This is a bug report for perl from cook@sightpath.com,
generated with the help of perlbug 1.26 running under perl 5.00503.


-----------------------------------------------------------------
[Please enter your report here]

Perl fails to reject this program:

 $a = 1,,,,,,,,

The superfluous commas just seem to be ignored.

The camel says these are wrong (so I'm told; p528?):

 print $a, if s/x/y/;
 print, if s/x/y/;

Yet perl accepts them.
