in thread Doing "it" only once

Not only: if print were really a longer portion of code, you may {want,need} to refactor it into a sub, with the added overhead of a sub call (and here we're being -for once- really paranoid 'bout efficiency and micro-optimizations), which would not have been necessary at all if we had that kind of syntactic sugar...
Well, that would ask for syntactic sugar with an overhead of less than a subroutine call....

Note that with clever use of string eval you can duplicate the code without having to maintain it twice, and not have the overhead of calling a subroutine from a loop. And you can move the eval as far out as you want (so the overhead of calling it becomes small enough).

    Of course my original question was asked in the context of Perl6, and there my reasoning goes one. Just as obviously eval is the answer to most self-modifying-code(-like) needs in Perl5, but we all rather prefer to avoid it if possible...
