This thread is about "same type" determination. The PURE thing is a 
separate (though related) discussion.

No. Compilers can warn about use of obsolescent features, documentation 
can move discussion of the features elsewhere or otherwise diminish 
their visibility, and textbook authors would be discouraged from 
teaching them. The standard shows obsolescent features in a smaller font.
