overloading by constness

Is this what you mean? Since const() and invariant() construct new types,
overloading should work just fine.

----
void foo(char[] str)
{ writefln("plain"); }

void foo(const(char[]) str)
{ writefln("const"); }

void main()
{
  char[] plainstr = "abc".dup;
  const(char[]) conststr = "abc";
        
  foo(plainstr); // prints plain
  foo(conststr); // prints const
}
