You can get the parent of an alias. The following template finds all 
overloads of a given symbol:

template ID(T...){alias    T ID;}
template getOverloads(alias f){
     enum fname = f.stringof[0..f.stringof.indexOf("(")];
     alias ID!(__traits(getOverloads, __traits(parent, f), fname)) 
getOverloads;
}

I think this should go into std.traits, as soon as it works. (DMD is 
buggy when it comes to taking the .stringof of a function. It 
misinterprets it as a property function call in some cases but not in 
others. Messy.)
