humm, I'm tempted to say multiplication is generally (if not
always) commutative too.
Anyway, some very interesting discussions, surely the point is that there
should be a concise explanation about string concatenation in the docs
somewhere, something like:
"you can do "hello"*"world" which is the same as string("hello", "world"),
the reason we don't use + is ..., for performance you should use IOBuffer
for repeated string concatenation, example..."
Also a more instructive error on "hello"+"world" would make since.
