Yes. This is my fear of hyperoperation being the default for normal aggregates. Loops--and large, multiply-nested, potentially-infinite ones--can spring out of code that doesn't look loopy at all. Erm... you know what I mean. :-) Karl, do you have any objection to marking aggregates for which hyperoperation is to be the default? Then you could say: my <mumble> @foo, @bar; # Are the parens required in p6? # or my (@foo, @bar) is <mumble>; # Can you distribute properties? <...> @foo += @bar; where <mumble> is matrix, hyper, or something along those lines (choosing great names is Larry, Damian and Allison's jobs, not mine :-) If we simply made such hyperoperated aggregates builtins rather than requiring user-defined classes, this would offer a compromise, would it not?
