opDispatch does accept additional template parameters but they cannot be
specified:

====
module test.d;

import std.stdio;

struct DispatchTest {
����void opDispatch(string name, string otherName)() {
��������writeln(name, ":", otherName);
����}
}

void main() {
����DispatchTest t;
����//t.testName!("testOtherName")();
����t.opDispatch!("testName", "testOtherName")();
}
====

�This compiles fine but if I remove the commented line, dmd (v2.048) tells�
me:

test.d(13): Error: template instance opDispatch!("testName") does not match�
template declaration opDispatch(string name,string otherName)

The error seems OK for a "normal" function, but for opDispatch, it seems�
limiting to me: the first call should translate to the second.

Here's an other, similar, test:

====
module test.d;

import std.stdio;

struct DispatchTest {
����void opDispatch(string name, T)(T t) {
��������writeln(name, ":", T.stringof);
����}
}

void main() {
����DispatchTest t;
����//t.testName!(DispatchTest)(t);
����t.testName(t);
}
====

Which gives, when uncommenting:

test.d(13): Error: template instance opDispatch!("testName") does not match�
template declaration opDispatch(string name,T).
