Yep, and here's the benchmarks to prove it. (I just felt like learning the benchmark module.)
use strict;
use warnings;
use Benchmark qw(:all);
#banging on the keyboard
my $target_string = 'al;nsdfj;oasmfdio;asdfoasdjfm;mioasfdsjdo;fijso;a
+dfjmio;sadjfmos;adfmjosia;mdfjiosad';
Benchmark::cmpthese (
1000000,
{
'substituteStar' => sub { $_ = $target_string;
s/[abc]*//g; } ,
'substituteNoStar' => sub { $_ = $target_string;
s/[abc]//g; } ,
'substitutePlus' => sub { $_ = $target_string;
s/[abc]+//g; } ,
'trAbc' => sub { $_ = $target_string;
tr/abc//d; }
}
)
Outputs:
