Hello,
Hopefully a very simple question. I am trying out RPython toolchain. pypy
2.6, python 2.7. I am using the translator shell.
Here's my simple example:
python bin/translatorshell.py
class mtype():
def __init__(self):
self.x = 0;
def mmm(x):
z = x.x + 1
return z
t = Translation(mmm, [mtype])
t.annotate()
and it gives me the following. if you put mtype class and mmm function
definitions in a separate module, then you can see it complains about this
line: z = x.x + 1. Why can't it infer type for all arguments and the
result here? I know i am missing something basic.
