It would certainly solve the problem of which keyword to use! :-) And
I think the syntax isn't even ambiguous -- the trailing colon
distinguishes this from the function decorator syntax. I guess it
would morph '@xxx' into "user-defined-keyword".
How would acquire be defined? I guess it could be this, returning a
function that takes a callable as an argument just like other
decorators:
def acquire(aLock):
def acquirer(block):
aLock.acquire()
try:
block()
finally:
aLock.release()
return acquirer
and the substitution of
@EXPR:
CODE
would become something like
def __block():
CODE
EXPR(__block)
I'm not yet sure whether to love or hate it. :-)
