Re: Merging hashes (clobber duplicate keys)

I find that @$a->{ EXPR } won't work, because it expects $a to be an ARRAY ref. @{ $a }{ EXPR } should be used instead.

Here's a slightly shorter version of your code: @{$a}{keys %b} = values %b; keys and values always return their results in corresponding order.

Here's an even shorter version: =) `@$a{ keys %b } = values %b;`	[reply] [d/l]

Re: `@{ }` Mea culpa ... That final code must be what I was trying to get my brain around. I knew there had to be a way without a temporary var... Thanks greatly.	[reply] [d/l]
