I wanted to show a variable-length value as a series of hex bytes. I wavered a moment between what I did (map each byte) and unpacking the whole thing as a hex string and then inserting spaces into that string.

Which is faster, more efficient, or otherwise better?

Hey, which is shorter!

sub hexout
 {
 join (' ', map { sprintf "%02x", $_ } (unpack ("C*", shift)));
 }
