I'd go for repeat every element twice. The general rule would be (if I were
making the rules... :) "things with an array on the left and a scalar on
the right apply the thing to each element of the array". So:
@foo * 12;
multiplies each element of @foo by twelve, and
@foo . "A";
concatenates an "A" on each element of @foo. This could be taken to
extremes, and I wouldn't propose that:
@foo gt "C";
returns a list of true or false values, one for each element of @foo.
(Though it could be useful, especially if it actually returned some sort of
quantum superposition...)
