Afaik free-function operator overloads (but not in the context of

I don't get it, aren't the current symbol lookup rules enough to make
free function operator overloads useful? To me it looks like they are.

Yup. It could be argued that it is essentially a compiler bug.
Sorry for digging up this thread, just getting irritated by a
restriction that seems pointless and arbitrary.

It is, but it has a few vocal proponents.
Overloaded operators would suffer from the same potential abuses other
methods are subjected to if UFCS was enabled, nothing more as far as I
can see.
You are perfectly right of course. It's painful for no benefit. (For
example, there's no way to overload e.g. '+=' for classes in a way that
reassigns the reference.)
