You didn't quote everything that is relevant:

Yes, necessarily.

Exactly.

The error message says

Error: template instance 
std.functional.binaryFunImpl!(pred,parm1Name,parm2Name).Body!(dchar,string) 
recursive expansion

Compare to:

template T1(int x){
     alias T1!(x+1) T1;
}

template T2(int x){
     alias T1!x T2;
}

void main(){
     mixin T2!0;
}

Error: template instance tt.T1!(500) recursive expansion

I'll attempt to analyse what is going on in detail tonight.
