Boolean Function - Definition?

[Jon Awbrey]

can't speak for what it is in oeis-land, but i have seen usages
where any function f : X -> Y where X or Y or both is some B^k
will be called a "boolean function".  i try to call things of
the form f : X -> B "boolean-valued".  calling B = {0, 1} by
the name GF(2) will often cause confusion, as some people
will use "+" to mean "or" instead of the proper field
addition.
