If we have:
def f(x) [function_that_takes_f]:
pass
what about an block-variant:
blockdef my_thing [function_that_takes_dict_of_the_block_definition]
...block...
so we could write:
blockdef myprop [property]:
def __get__(self):
return ...
def __set__(self, value):
...
def __delete__(self):
...
(replace blockdef with your favorite new keyword...)
