In Python, "+" does not

infix line of code that includes "obj1 + obj2" is supposed to investigate

it does a sequence of operations till it finds what it needs and does it.
A really nice example of this is pathlib in the standard library. You
can write things like this, overloading the "/" operator:
>>> from pathlib import PurePath
>>> pth = PurePath('c:/') / 'temp' / 'python'
>>> pth
PureWindowsPath('c:/temp/python')
>>> str(pth)
'c:\\temp\\python'
