Oups, that was a new file, and thus it wasn't part of the diff.
I attach it now for the record.

The Unary_expr_block harness expects a functor that is a class template
taking a single parameter. As here we have three, I put the two additional
parameters in the outer 'wrapper' template. I'm looking forward to times
when template typedefs become available. :-)

The patch is checked in now.
