Not in so many words, but there are limitations on what you can do based on

But so long as you meet those semantics, you can implement t

Im reading about bitwise operators and is it true to say they dont work 100% as
in C?
bitwise operators in C seem to result in bits going to the so called bitbucket.
For example, 0b0001. Shifting it >> 1 in C it seems to add on zero to the
left and the 1 to the right gets throwned away.

- I go to the 'File' menu;
- I select the 'New File' option
- IDLE quits.
I run the IDLE version 3.3.3 on Windows 8.1 Pro.
