I have, on rare occasion, found use for the `$list[@list] = ...' syntax, where push would not make sense.

More idiomatically, the first snippet should be reduced to the following:
  
my @result = map "$_:$hash{ $_ }", keys %hash

I have a hunch that the coder didn't really want an array sorted in the arbitrary order that keys happens to return, and that this is actually part of a larger body of nonsense :)

The second snippet is an absolute abomination of sanity checking code, which is exactly the sort of thing I was warning you about here :-p

update: Whoops, just noticed that maverick already pointed out the map idiomatization.
