Even though I think it's a questionable feature, the fact that popular
Scheme implementations already implement #; is a strong argument in
favor of standardizing it with a SRFI.  The SRFI only mentions this is
passing, in "This syntax is already in wide use".  I suggest mentioning
the "existing art" more prominently in the Rationale, perhaps listing
known implementations that provide the feature.
