Thats it! I love it. I like the following variation even better: def foo() | classmethod | accepts(int, int) | returns(float): Alternatively, def foo() | classmethod | accepts(int, int) | returns(float): Yes, I understand that the first of these would require allowing a newline after the | without ending the statement. If it were up to me, I would allow a newline to follow any operator, but if that's too radical, then allowing newlines between the def and the following : would be fine.

I just anted to rewrite those "real-life-looking" examples with my proposed '%' syntax:

def foo() % (classmethod, accepts(int,int), returns(float),):

or formatted:

def foo() % ( classmethod, accepts(int,int), returns(float),):

Or it can be done the this way:

def foo(): ...

foo %= (classmethod, accepts(int,int), returns(float),)

The operation could be called "decorative apply", if the LHS has call attribute. Just a new form of % operation with special syntax for "def" operator.

Sincerely yours, Roman Suzi
