I often find myself doing something similar to the following (usually
when I want to return multiple things from a function)
>>> class Struct:
... pass
...
>>> p = Struct()
>>> p.x = 10
>>> p.y = 11
>>> p.color = 'blue'
That's slightly more verbose than you're proposed syntax but doesn't
usually feel to onerous (especially since you only have to declare the
Struct class once). If you like everything on one line you could do:
>>> p = Struct(); p.x = 10; p.y = 11; p.color = 'blue'
