Re: HoA create from array using map, more efficient?

Fyi, this:

 ($k,$v) = (split /\s+/,$_)[2,4];
[download]

is equivalent to:


my ($snap, $rotation) = (split)[2,4];
[download]

Also, use my() variables rather than global variables.

...which means you didn't use strict and warnings, which you should be doing too.

There is a difference between the two, but it doesn't matter here since there's never any leading whitespace.	[reply]

Thanks, the implicit split is better... also, yes that script runs under strictures (I didn't show the whole script obviously) -- I just declared ($k,$v) globally because I use them in a bunch of other places - maybe that's a bad idea but they get overwritten each time, and values are coming back correctly. Maybe that's a bad idea no matter how short the script?	[reply]

Avoid the `my` is surely a premature optimisation that can only hurt you.	[reply] [d/l]
