I'm not sure the XX thing will happen, but if it does, it'd be most
useful if it wouldn't treat a sub call differently.
In other words,
@random = { rand } XX 5;
would return 5 different random values, while
@random = { rand }() XX 5;
would do exactly the same as
@random = rand xx 5;
And your
@names = &get_next(...) XX 5; # Why the &, by the way?
I think should be
@names = { get_next(...) } XX 5;
or, if get_next doesn't take arguments,
@names = &get_next XX 5;
Note that if the ... should change each of the 5 times, then this should
be done using map:
1..5 ==> map { get_next($_) } ==> @names;
or of course
@names = map { get_next($_) }, 1..5;
The XX was proposed mainly because the 1..5 part of map often does not
make sense as a range, and in those cases you just abuse it for
repetition.
