Addresses GB-87
There is no compelling reason to assume a heterogeneous tuple of two elements holds a pair of iterators forming a valid range. Unlike std::pair, there are no functions in the standard library using this as a return type with a valid range, so there is even less reason to try to adapt this type for the new for-loop syntax.
[ Resolved in Rapperswil by a motion to directly apply the words from the ballot comment in N3102. ]
Proposed resolution:
Strike 20.4.2.10 and the matching declarations in the header synopsis in 20.4.
