"""
I found something new today.
I find myself often missing the ++ operator in python
especially when I am wanting to assign values in tests
and would rather have an incrementing variable
"""

test_val = SomeClass(id=0)
another_val = SomeClass(id=1)
last_val = SomeClass(id=2)

"""
Obviously, if you have enough test vals, it gets annoying.
Also, the hard-coded sequence will be even more annoying if
you want to insert a line in there and want your numbering
to be sequential.

In c/c++/java/C# you would use the ++ operator to get the
current value of a counter and then increment it.

I just found the count() function from itertools in python.
Now, you can get incr equivalent functionality
"""
import itertools
i = itertools.count()
test_val = some_class(id=next(i))
another_val = some_class(id=next(i))
last_val = some_class(id=next(i))
