Re^3: Benchmark: Constant List in Hash Slice

does this also explain why using a normal @array variable is faster than a constant list?

No. That's because constant arrays are implemented as constant array refs. So

use constant foo qw(a b c);
@a = $h{foo()}
[download]

is implemented roughly as

use constant foo [qw(a b c)];
@a = $h{@{foo()}}
[download]

And neither (as far as I'm aware) get the compile-time HEK treatment

Oh that's good to know, thanks! :) Hence constant arrays won't help much for tuning performance. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]
