I agree, but I think we should explicitly say so.  It didn't matter in
R5RS, because eval-ing a definition was undefined.

My preliminary proposal for this is at MutableEnvironmentsCurtisCowan.

I must confess that I have very little notion of what [s. 4 of the British
Trade Marks Act, 1938] is intended to convey, and particularly the sentence
of 253 words, as I make them, which constitutes sub-section 1.  I doubt if
the entire statute book could be successfully searched for a sentence of
equal length which is of more fuliginous obscurity. --MacKinnon LJ, 1940
