In Python 3, 'print' was changed from a statement to a function. Using
the __future__ module allows scripts to use print function whether
running with Python 2.6+ or Python 3.x. This commit changes as many
instances of print as I could find to use the print function and the
__future__ module.
This reflects the fact that the attribute's only for compiler-internal use, and isn't really equivalent to C's asm attribute, since it doesn't change the calling convention to be C-compatible.
Currently it's in early development stage, and is not intented for
massive usage.
