I'm just starting to get to grips with
map and wondering what more I can do with it. Is it possible to do conditional mapping? To take the example in
map, say I have an array
my @array = qw/
foo
bar
baz
bodkin
/;
and I want to make a hash using all but words beginning in 'f' as values,
my %hash2 = ();
foreach $_ (@array) {
$hash2{getkey($_)} = $_ unless /^f/;
}
works, but is there an equivalent usage with
map?
my %hash1 = map {getkey($_) => $_ unless /^f/} @array;
doesn't work.
Am I barking up the wrong tree? Which tree would you recommend?
