++ Top-level infinity
++ Default infinity signatures for the interpreter;
Infinity() : SIG == CODE where
SIG ==> with
infinity : () -> OnePointCompletion Integer
++ infinity() returns infinity.
plusInfinity : () -> OrderedCompletion Integer
++ plusInfinity() returns plusIinfinity.
minusInfinity : () -> OrderedCompletion Integer
++ minusInfinity() returns minusInfinity.
CODE ==> add
infinity() == infinity()$OnePointCompletion(Integer)
plusInfinity() == plusInfinity()$OrderedCompletion(Integer)
minusInfinity() == minusInfinity()$OrderedCompletion(Integer)
