Reply to Denis,

Back on topic, I don't see anything wrong with this code. It defines
exactly one alias.
 I also think that it should define exactly one /public/ alias:
 template Blah(T)
{
private alias Foo!(T).A Tmp1;
private alias Bar!(Tmp1!(T)).B Tmp2;
static if (Tmp2.C!(T)) {
private alias Tmp2.ResultA Tmp3;
} else {
private alias Tmp2.ResultB Tmp3;
}
/*public*/ alias Tmp3!(Tmp2!(Tmp1!())).C Blah; }

That covers my one major concern with the exactly one rule; local values.

OTOH I have used template with many public value as a type of compile time structs. It's an absolute must for anything thing that require data structures like parsing of strings.

You could use a tuple or struct for that purpose:

template Blah(Stuff)
{
   struct Blah
   {
       // code that defines multiple symbols here
   }
}
