Ahh.  But then, constants aren't method calls, so
why doesn't something like this work:

    irb(main):002:0> FalseClass ? 0 : 1
    0

No surprise, right?  Then why does this happen:

    irb(main):003:0> FalseClass?0:1    
    SyntaxError: compile error
    (irb):3: parse error
    FalseClass?0:1
                 ^
            from (irb):3

The compiler should know that FalseClass is a constant and
therefore isn't a method call, so the "?" is the operator
and should be a seperate token.
