I'm suggesting the addition of support to using a dot notation when
defining a function to be a method of a class, or a callback attribute. For
example:
def foo(self):
pass
Foo.foo = foo
Becomes:
def Foo.foo(self):
pass
Other syntaxes can also be used if the dot itself is an issue, although I
dislike these:
def Foo:foo(self):
def foo@Foo(self):
def Foo>foo(self):
def Foo&foo(self):
This functionality would be useful in the few rare cases where the class
itself needs to be accessed in the function's definition (decorator,
typing, etc.):
@barify(Foo)
def Foo.method(self, other: Foo) -> Foo:
pass
And when an object needs a callback as an attribute:
class Menu:
def __init__(self, items=None, select_callback=None):
self.items = items if items is not None else []
self.select_callback = select_callback
my_menu = Menu([item1, item2])
def my_menu.select_callback(self, item_index):
print(self.items[item_index])
As opposed to:
my_menu = Menu([item1, item2])
def select_callback(self, item_index):
print(self.items[item_index])
my_menu.select_callback = select_callback
Or defining them in "unnatural" order:
def select_callback(self, item_index):
print(self.items[item_index])
my_menu = Menu([item1, item2], select_callback)
