[ID 20000413.002] prototype for optional coderef parameter

This is a bug report for perl from siegel@zrz.tu-berlin.de,
generated with the help of perlbug 1.28 running under perl v5.6.0.


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


Please watch this:

perl -e 'sub foo (;&) {} foo {};'
Type of arg 1 to main::foo must be block (not single ref constructor) at -e line 1, near "};"

Calling foo with a bare block should be possible, at least perlsub doesn't
say otherwise.  The error goes away when you make the coderef parameter
required, changing "(;&)" to "(&)".

The bug, if it is a bug, was present in Perl 5.5 as well, though the
message said "(not scalar ref constructor)" instead of "...single...".
