This is a bug report for perl from dean.herington@emc.com,
generated with the help of perlbug 1.39 running under perl 5.16.3.


-----------------------------------------------------------------
I don't understand the following error.  I think the result of the
following statement should be the same as the similar one shown later.

  DB<1> p map { a => 1 } 1,2,3
Not enough arguments for map at (eval 9)[C:/Perl/lib/perl5db.pl:646] line 2, near "} 1"
syntax error at (eval 9)[C:/Perl/lib/perl5db.pl:646] line 2, near "} 1"

  DB<2> $a = 'a'

  DB<3> p map { $a => 1 } 1,2,3
a1a1a1
