What's suboptimal about the proxy case here?

This seems to get way off-topic for the liaison list, btw.

The only part of the proposal that affects the common
subset of C and C++ is the fact that the comma operator
can no longer be used unparenthesized inside [].

Other than that, this is a user-defined overloaded operator,
a feature that C doesn't have. Hardly any extension for
built-in types that C might contemplate is precluded by that.
