Eiffel, C++, Ada fall all in the same category here.
See Dylan or standard CLOS dispatching. That's what I'd like. And it
doesn't
mean that also having restricted single dispatch would not be possible.

The word about multimethods seem to be spreading. Ada95 embraced OO.
Is a new round scheduled? And the poll is; "Who wants that?"

Ada has an edge here w.r.t. Eiffel and C++ regarding adoption of multi
dispatch.
Extending the others will imply having them look gratuitously asymmetric or
increase
in complexity. Resolving how that would interplay with overloading in C++
will be an issue.
Eiffel uses classes as the unit of encapsulation. That is weird for
multimethods. Not to say
anything about extensibility.
