The task is not correct. "and returns true only if the function in the params returns true for exactly one (1) item in the sequence." The function can return something like "yes" and you should see at as True, otherwhise some tests fail.

Language: C
Error messages are unclear.
The expression (one(((void*)0), 0, &always_true)) == (0) is false.As a 7kyu kata, I Suggest fixing error messages for clearer understanding of the errors.
kreative kata
this issue concerns the programming languge of C. this issue is not a big deal. this issue is that tests generate warnings. here is a paste of the warnings:
Hi everybody! Guys, Im newbie here and I try to figure out how do tasks (katas) here. The question is: can I use only one function that i got at preconditions(from the start of a task) in SOLUTION table or I can create another one if needed?
so long as you don't have a naming conflict, you can create multiple helper functions outside of the main kata function and use them in any way you want. of course, in python you can also create functions that are nested within the main kata function.

I think the description can be improved to make it a bit more clear what is expected.
Original: Create a method one? that accepts a list and a block, and returns true only if the block returns true exactly one (and only one) item in the array.
Modified: Create a method one? that accepts two params, a list and a block, and returns true only if the block returns true for exactly one item in the array.
As a native English speaker, this change makes it clearer, and doesn't require the extra '(and only one)" qualifier.
