in reply to Re^8: Perl is dying (better sorting than the ST)
in thread Perl is dying

Yeah. The idea is that a tuple is immutable; once it’s been constructed, it can no longer be modified. In that case, perl does know the extent of the data structure: it’s the extent of the data structure at the time of its construction.

It would have more applications than just map, too. The idea’s not bad. (Of course it doesn’t redeem the ST in my opinion…)

Makeshifts last the longest.
