in reply to Formatting dynamic method names

sub temp_var { for ( keys %hash ) { my $method = "set_$_"; $object->$method( $hash{$_} ); } }
This benchmark code also includes the creation of a lexical scalar as well as assignment to it. The benchmark would be slightly more accurate (and slightly faster) if the lexical were defined outside the loop and used inside. (However, I doubt the speed difference would be significant.)

I would agree with zwon in preferring the 'temp var' approach.

    Interesting - here are the results:

    Rate deref temp_var reused_lexic +al deref 173010/s -- -21% -2 +7% temp_var 218818/s 26% -- - +8% reused_lexical 238095/s 38% 9% +--

    (Note: these benchmarks are for interest only, and are firmly in the field of premature optimization)
