For sure, SRFI 77 doesn't have 32-bit or 64-bit integers *as types*.
(And that would cause major pain with the way Scheme's arithmetic is
generally set up.) However, it does have the necessary operations to
easily implement 32-bit or 64-bit unsigned or two's complement
arithmetic in the form of `div+mod' and `div0+mod0' operations. As
such, it also has bit operations on them.
SRFI 77 doesn't have, but R6RS will have, support for "unboxed arrays"
of numbers in the form of a variation on SRFI 74. I'm not sure they
qualify as "uniform," but is the uniformity crucial to your

As it stands currently (may not be the final word), the intro to that
section in R6RS will have a sentence specifying case insensitivity for
