migen.fhdl.size: add fiter(), fslice(), and freversed() do not overload __len__, __iter__, __reversed__ as not all valid expressions (ints and bools) have them. furthermore len([]) is and should be different from flen([]) (the later raises an error). keep __getitem__ as an exception that proves the rule ;) 2013-12-02 19:19:32 -05:00			`import unittest`
