Re^3: Error: when joining two hashes

You can't call keys on an array so that's not going to do anything useful. There's a slight whiff of an XY problem in that your data in the two variables isn't of the same shape (HoH vs AoHoH); it might help if you step back a notch and figure out why your previous step(s) aren't making the same outputs.

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' 0 1 2 3` [download] But yeah, in this context it's not useful.	[reply] [d/l] [select]

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]
