Python 3.0a2 (r30a2:59405M, Dec 7 2007
>>> apply
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'apply' is not defined
I understand it's "To be removed" [1]. These proposals are similar
[2] [3].
What is not in is a full-fledged anonymous function. That is a code
block.
I personally have been focussing on multi-threading, looking to the
future, so forgive the one-sided example.
@start_new_thread
def anonA():
normal_suite()
Similar.
start_new_thread():
normal_suite()
Or, if you're using other arguments, or the function does not take a
function as its first parameter, rearrange parameters with a standard
function.
Makes it hard to join or call if you ever need it more than once. I
don't believe that assigning the return to a name fits in with the
grand scheme.
Yes:
def convenientstart( func ):
Thread( target= func ).start()
@convenientstart
def anonA():
normal_suite()
Yes:
def convenientstart( func ):
th= Thread( target= func, args= ( th, ) )
th.start()
return th#, but where does it go?
convenientstart():
normal_suite()
No:
def convenientstart( func ):
Thread( target= func ).start()
convenientstart() as thA:
normal_suite()
I dream:
def convenientstart( func, A ):
th= Thread( target= func, args= ( th, A ) )
th.start()
return th#, but where does it go?
th= convenientstart( A ):
normal_suite()
Cf. bound object instance calls: code block is the applicable "self".
Another day, perhaps.
I am extremely open to feedback. Asking to brainstorm. Thoughts
welcome. Any?
