Most of the operators are supported (is there any missing aside from the __i*__ ones?), operator-based unaries (+, - and ~) are supported as well, but
All operators are handled, the rest (aside from __index__ maybe) will be supported as the corresponding builtins are implemented (e.g. __float__ is already used if present).
__i*__ forms are and will remain unsupported as they're assignments, and thus a statement.
