Speaking of library solutions, I checked with my `castSwitch`
PR and it managed to implement single-argument multi-dispatch:

I'll try to get it to support multiple arguments(shouldn't be
that hard) and then all we'll need is a simple wrapper to have
our very own library implemented single dispatch.
I'm thinking we'll want two versions - a regular templated
function like in Vladimir's reply, and also a template mixin
that can take a bunch of methods with the same name(or
annotated with a UDA) and create a multi-method of them.
These wrappers will be another PR, but they can be based on
`castSwitch` for it's somewhat-optimized type-comparison
implementation.
Damn, that is really nice! I was wondering when we'd see
something like this make its way into the standard library. :)
