I also think that the paragraph proposing (srfi 113 ordered) and (srfi 113 hash) should be dropped and a new SRFI created that will provide these libraries, along with the set analogues of OrderedMapsCowan.
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
