Are Go's integers unbounded? If not, proving the value never exceeds the range to silent convert essentially a BigInteger into an int might be hard.

Go tends to use machine sizes like C, but this implementation appears to properly handle it. The following Python code has identical output for me under Python and grumpy:

    two_32 = 4294967296
    print(two_32 * two_32)
    print(type(two_32 * two_32))
And I tested some other things I won't burden HN with, but promotion is implemented, yes.
