I'm looking for a way to condense this: 
my $combined;

if ($a) {
   $combined .= "a=$a ";
}
if ($b) {
   $combined .= "b=$b ";
}
if ($c) {
   $combined .= "c=$c ";
}
...
...
...

I'm just not sure how to approach it. I thought I could use map, but I'm not sure how: 
my $combined = map { ??? } qw($a $b $c ...);

I would appreciate any ideas. Thanks.
