indexing tuples using strings

This has to change in D2. Perl shows why that's bad. To replace all the current semantics you can just to add a syntax that performs as an 'apply' (Python uses a * for this, but D probably needs a different syntax).

Time ago I have created some machinery to represent arbitrarily nested "arrays" into a tuple, using an encoding that can represent all the lengths of the sub-sub-sub-etc "arrays", but it's complex, and probably uses too much resources during compile-time, so something more native is better.
