Actually, that syntax only works for regular templates, not 
mixins. Trying it with a mixin template gives an error. It's also 
not very useful when mixing in several methods from the same 
template.

However, the first solution I suggested could be expanded to 
support that type of syntax:

struct HasMixins {
   alias mixin someMixin!int.abc abc;
   //etc.
}

I'm starting to lean toward the first option as the more 
"correct" solution because it's more flexible and follows the 
principle of least surprise. If it's decided that this would be 
an acceptable addition to the language, I could try to cobble a 
pull request together. I don't have any experience with the DMD 
codebase, but it might be a good introductory project for me...
