New submission from Arvin Moezzi:

I am not sure if this is the right way to do it but IMHO it would be great to
have a function decorator/transformer to make functions partial applicable
using functools.partial. Like

from functools import partial

class partial_applicable():
	def __call__(self, func):
		def __wrapper(*args, **kvargs):
				return func(*args, **kvargs)
			except TypeError:
				return partial(func, *args, **kvargs)

		return __wrapper

Then you could do like:

def substract(left, right):
	return left - right

substract(10, 100) 
 => -90

rclose = substract(right = 1000)
 => rclose(10) => -990

lclose = substract(1)
 => lclose(10) => -9

What do you think?
