Re^4: Error: when joining two hashes

You can't call keys on an array so that's not going to do anything useful.

As of 5.12 (2010), keys @array returns the indicies of the array.

$ perl -wMstrict -le 'my @x=qw/a b c d/; print for keys @x'

But yeah, in this context it's not useful.

Derp! I stand corrected there (and should have read my own link first); it's just the difference in shapes and depths of the values means it's not going to do anything useful. The cake is a lie. The cake is a lie. The cake is a lie.	[reply]
