short-hand for same regex for multiple scalars?

[Alexander Huber]

Hi,

Is there a shorter way of writing the following (regex only once on
right-hand side?), basically I want to apply the same regular expression
consecutively to multiple scalars:

$a =~ s/a/b/gs;
$b =~ s/a/b/gs;
$c =~ s/a/b/gs;

Thanks,

Alexander.

Why not just use a loop?

for my $var ($a, $b, $c) {
$var =~ s/a/b/gs;
}

for my $var ($a, $b, $c) {
$var =~ s/a/b/gs;
}

Since the OP wants a shorter way:

s/a/b/g for $a, $b, $c;

s/a/b/g for $a, $b, $c;

It should also be noted that the very fact that the OP wants to perform
idenitical processing on several scalar values means he should consider
putting them in a agregate data type rather than separately named
scalars.

s/a/b/g for values %some_hash;
