What is this? It looks like you are trying to use a list as a hash key. I don't
think that is going to work. A hash element should take a scalar as its key, not a
list:
Greetings! C:\Documents and Settings\rjnewton>perl -w
my %hash = (first => 'one thing', second => 'another', third => 'still another')
;
foreach $try_a_key ($hash{keys %hash}) {
print "$try_a_key\n";
}
^Z
Use of uninitialized value in concatenation (.) or string at - line 3.
There is one, sorta quirky, way that it can work, though:
Greetings! C:\Documents and Settings\rjnewton>perl -w
my %hash = (first => 'one thing', second => 'another', 3 => 'still another');
foreach $try_a_key ($hash{keys %hash}) {
print "$try_a_key\n";
}
^Z
still another
Of course, in the above, the foreach is superfluous, since this syntax willalway put
one or fewer items in the list.
Is that what you were looking for--something keyed to the number of keys in a hash?
Otherwise, you may have to go back and define your goal and steps to reach it more
clearly.
