That convention is available in Scheme also, by passing a
bytevector of length 8 as the second argument and extracting
the result via bytevector-ieee-double-native-ref or similar.

If you insist upon this point, I will correct the sample
implementation and Larceny's implementation of SRFI 144 so they
require programmers to pass an 8-element bytevector as second
argument to the

    flinteger-fraction
    flnormalized-fraction-exponent
    flloggamma

procedures and as a third argument to the flremquo procedure.
