Re: Unexpected difference in whitespace parsing in subroutine calls.

in reply to Unexpected difference in whitespace parsing in subroutine calls.

If we deparse this to see how perl will it makes a certain kind of sense

## deparse output as deparsed by -MO=Deparse,-p
print(sort(f(0)));   # case 1
print((sort f 0));   # case 2
print(sort(&f(0)));  # case 3
print((sort f 0));   # case 4
print((sort f 0));   # case 5
print(sort(&f(0)));  # case 6
sub f {
    1;
}
- syntax OK

So, cases 1, 3 and 6 all behave the same (i.e call f) and cases 2, 4 and 5 behave the same (i.e sort on 0, which, as a single element list, is already sorted, so f isn't called). And that's the end of that chapter.
