    I realize you said that you do not like semi-colons, but it seems to me
that your use of a period as a statement seperator has its own problems.
Consider the following:

        print 1.

    In Python, that is printing a floating point number. In Pixy, that is
printing an integer. Now, It'd be all fine and dandy to just make it a
language requirement that all floating points *have* a number after the
decimal point, but it eats at the clairity and starts looking uncool:

        print 1.0.

    Just an example. :)
