All projects that implement such compilers prove that it's quite possible. The most widely used static Python compiler is Cython, but there are also a couple of experimental compilers that do similar things in more or less useful or usable ways. And there are also a couple of projects that do dynamic runtime compilation, most notably PyPy and Numba. You may want to take a look at the Python implementations page, specifically the list of Python compilers: http://wiki.python.org/moin/PythonImplementations#Compilers > Does machinecode always need to know whether a variable is an int or a > float? Not at all. You're mixing different levels of abstraction here. > And if so, can't you build a compiler which creates machinecode > that can handle both ints and floats in case of doubt? Sure. Cython does just that, for example, unless you tell it explicitly to restrict a variable to a specific type. Basically, you get Python semantics by default and C semantics if you want to.
