There was the discussion about vector, etc...
I think I have a frustration about chaining things easily in python in
the stdlib where many libs like orm do it great.
Here an example :
The code is useless, just to show the idea
>>> a = [1,2,3]
>>> c = max(a) + 1
I would be happy to have
>>> [1,2,3].append(4)::sort()::max() +1
It makes things very easy to read: first create list, then append 4,
then sort, then get the max.
To resume, the idea is to apply via a new operator (::, .., etc...) the
following callable on the previous object. It's clearly for standalone
object or after a method call when the return is None (there is fluent
`.` when there is a return value)
>> object::callable() = callable(object)
>> object(arg)::callable = callable(object(arg))
>> object::callable(arg) == callable(object, arg)
The idea is to use quite everything as first argument of any callable.
I do not know if it was already discussed, and if it would be
