Would you believe it? Your implementation works just fine in this case too
:-) sysmodule.c invokes PyFrame_FastToLocals and PyFrame_LocalsToFast around
a call to a trace function, so that any change to f_locals from the trace
function are actually correctly reflected into the frame.
Excellent. Let's put this in the standard library and close the issue ;-)
As an easy extension, decorate(attr=value, ...) could just assign attributes
to the function object. Also, the fact that it works with other assignment
statements is a bonus in my opinion, e.g.:
class X:
decorate(doc("Number of instances created."))
counter = 0
def __init__(self):
X.counter += 1
However, it gets a bit lost if several variables are assigned to in one line.
A bientot,
Armin.
