Discussion:

527 Added a throws clause to bind constructors. I believe the same throws clause should be added to tuple except it ought to take into account move constructors as well.

Proposed resolution:

Add to 22.4.4.1 [tuple.cnstr]:

For each tuple constructor and assignment operator, an exception is thrown only if the construction or assignment of one of the types in Types throws an exception.
