Thanks. On the basis of that test it does look to be quite a hit.

It'd be quite instructive to see the differences in the code paths (at the C or assembler level), when you do push @arr, 1; between the two builds.

I've never built a non-threaded Perl here as with no concurrency at all, it's almost pointless, but maybe I should and try to trace the code through.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
