Hi,

Aha, good point about IOError encapsulating other things, I'll use

And yes, I didn't use the exception object in my sample - I just sort. I'd

Note that you have to hit enter *twice* for this to work. (I'm not
sure why; the caret is supposed to escape the newline, but that
doesn't explain this. For all I know, it could be an ascended bug[1].)

Just because the CPython implementation does something doesn't mean that thing

Hi all,
I'm trying to wrap my head around how classes are constructed at the
interpreter level (as a side effect of digging into metaclasses) and
I'm hoping to have my investigation either validated or ridiculed ;)
The pipeline that I've figured through some gdb debugging (starting at
type_call):
Try typing this into IDLE:
>>> def a():
def b():
nonlocal q
SyntaxError: no binding for nonlocal 'q' found
In interactive command-line Python, this doesn't throw an error, and
it works fine if the name is used later:
>>> def a():
def b():
nonlocal q
q+=1
q=1
