[isabelle-dev] Unqualified swap?

In 8f1e7596deb7 I have introduced

	swap :: 'a * 'b => 'b * 'a

on products.

Is this common enough to be left unqualified?  I hesitated to qualify it
since Product_Type.swap is too cumbersome (although something different
could be achieved using low-level namespace manipulation).

(One might ask whether the _Type suffix on Product_Type.thy (and Sum.thy
and some others in Library/) should be discontinued then, but this is
another question)

Any remarks?
