If you really don't like the temporary array - doesn't seem so bad to me - you could use something like:

my $i = 0; # or whatever
$record[$i++]->{bytes} = $_ for get_bytes($num);

or perhaps, if you're just building the list:

push @record, map { {bytes => $_} } get_bytes($num);

[download]

but that won't be much good if you're working with an existing data structure. In that case i don't see a way of shrinking it to one line - and suspect that even if you find one, you'd regret the obfuscation later.

update just tried mr robot's solution and found, to my surprise, that the double curlies aren't required. I would have expected

@a = map { k => $_ } (1..3);

[download]

to give you (k,1,k,2,k,3), but no: it creates an array of hashrefs. so either that isn't a block at all - but where's the comma? - or there is such a thing as hash context after all. nice bit of dwimming. still borks any other key that previously existed in the hash, though.

update^2 don't know what i was thinking there. sauoq is quite right. odd that i remember it working, but clearly it doesn't :(
