Thanks, but what if the hash already has some values, like:
#! /usr/bin/perl

@a = qw(a b c d );
$b{x} = 10 ;

%b = map { $_, 1} splice(@a, 0, scalar(@a) );

print "$_ --> $b{$_}\n" foreach (keys %b) ;

[download]
all values of %b are erased using map.....
Furthermore, is scalar(@a) really necessary, or can you as well do @a ?
