I'm not convinced about this bug. Why do you think that struct literals should
become rvalues (rather than non-modifiable lvalues)? It's a breaking change.

You've mentioned opEquals, but it's much broader than that. Fairly obviously it
also affects opCmp, but in fact, any function which takes a struct by const ref
will currently accept a struct literal.

Also, what about member functions? 'this' is passed by reference, yet you can
use CTFE on member functions of struct literals.

It's clearly a bug to allow a struct literal to be passed by non-const
reference, but as to making them rvalues, I'm not sure. This needs confirmation
from Walter.
