Actually, the big one for me that's missing is autovivification.

The other day I had a list of co-ordinates (pulled from a DB as a record set). To put them into a grid, I simply did this:

my @grid;
foreach my $rec (@records) {
   $grid[$rec->{x}][$rec->{y}] = $rec;
}
[download]

That would've been a lot harder in most other languages.

Adding `grow(grid, $rec->{x}); grow(grid[$rec->{x}], $rec->{y});` [download] is not that complicated. Personally, I wish auto-vivification was off by default, and togglable using a lexical pragma.	[reply] [d/l]

I probably wouldn't have voted for autoviv if it were on the list, but the one time I needed it (as opposed to "cute, but wasn't necessary") it saved me the bother of writing a whole other subroutine. So yeah, can be very useful.	[reply]
