This is a spinoff of issue 6365


This program compiles and runs with no errors (it doesn't assert), DMD 2.054:


import std.typetuple;
void main() {
    TypeTuple!(int, int) f = 10;
    assert(f[0] == 10);
    assert(f[1] == 10);
}


The idea of carring this broken TypeTuple semantics over to Tuples too is icky.
I instead suggest to turn this into a compile-time error.
