for 99% of cases this is not a hindrance, but sometimes we'd rather be able to use full expression syntax. consider the following example (using PyQt):

    # make 10 buttons

    buttons = [QPushButton(f'button #{i}') for i in range(10)]

    # for now we only want to bind an event to the first button

    @buttons[0].clicked.connect

    def foo():

        ... # do whatever

in cases such as this, it would be useful to have any expression acceptable as a decorator.

In addition to other use cases such as chained function calling (@buttons_dict.get("foo"). clicked.connect), the restrictiveness of the decorator syntax seems like a strange oversight. Arbitrary expressions are already allowed in decorator lines as arguments, so allowing them as the called decorator shouldn't be too difficult.

Any thoughts on this?
