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:
