@brodiemark, that error message is both accurate and fair. You defined a repr that is indistinguishable from int and then your complaint is that your repr is indistinguishable from int. It's also explicitly stated in repr's docs that you shouldn't do that.

Okay, I see. Thank you.

Your solution returns the number passed in, so add(1) returns 1 - if you then do add(1)(2), you're trying to call the number 1 as a function, which causes the error.

Can not run it in Python 3.11, I just keep getting this error:

Unexpected exception raised

Traceback (most recent call last):

test.assert_equals(add(1)(2), 3)
^^^^^^^^^
TypeError: 'int' object is not callable

That might be the intention, but the quotes don't seem to be displayed in some situations.
If you remove the eq method from my solution in "View Solution" above, you'll see test results as in my first message.

If you return a string instead of a number the error message is like this in Python:

'1' should equal 1

And you should note the quotes around the first value. Unless I'm missing something.

Great problem! Learned a lot.

Suggestion (for Python): The tests can fail with the following unhelpful results:

1 should equal 1
3 should equal 3
6 should equal 6

What's happening here is that one of the 1's is an integer and the other is a string. It would be nice if the tests detected this and pointed it out.

Task clearly states that we need to create a function, yet all of the solutions are classes. Its nonsense.

Uhhh.... 4 kyu?

Oh, thank you. I was starting to overload all the other operators. Didn't thought about <<.

The [unsupported type] thing is a problem with the C++ testing framework. You can fix the messages by adding operator << to your class:

std::ostream& operator<<(std::ostream& os, const Add& add) {
  return os << add.get_n();
}

As to why it returns wrong result, I do not know yet.

I pass the first 6 tests (a_single_call_should_compare_equal_to_the_number_passed_in, must_be_able_to_store_curried_functions, must_be_able_to_store_values, must_be_usable_in_a_normal_addition, must_be_usable_in_a_normal_subtraction and should_pass_some_example_tests). In particular, I pass all examples given in the kata-instruction.

However, the last test (should_pass_some_tests_with_random_data) fails with

Expected: equal to 1313
Actual: [unsupported type]

I don't know what needs to be supported in addition. Am I supposed to figure this out on my own?

Yes, it is.
