This works wonderfully for opIndexAssign, but not so much for multiple 
types of aliases for opIndex.

    alias opIndex_T!(int).opIndex opIndex;
    alias opIndex_T!(float).opIndex opIndex;

test.d(54): function alias opIndex called with argument types:
        (char[3])
matches both:
        test.ValueContainer.opIndex_T!(int).opIndex(char[])
and:
        test.ValueContainer.opIndex_T!(float).opIndex(char[])
test.d(55): function alias opIndex called with argument types:
        (char[3])
matches both:
        test.ValueContainer.opIndex_T!(int).opIndex(char[])
and:
        test.ValueContainer.opIndex_T!(float).opIndex(char[])
test.d(56): function expected before (), not 0 of type int

So close...
