This is a side effect of part of the mechanism used to
implement bound methods. It's probably best to regard it
as an implementation detail subject to change.

There are clearer, more reliable and more general ways
to get currying if you want it, e.g.

   def foo(x):
     def foo2(y):
       ...do something with x and y
     return foo2
