The function force should be called before defining the constraint function, not inside the definition of the constraint function.
Not using forcemay not cause any problems. However, it's better to "force" because the constraint function is used by several other functions.
DONE. Checked and confirmed that force is not needed because all the names are evaluated before defining the function. No risk of lazy evaluation. Lines with force were deleted (11efb762f0b045d59e0c37a04c02fab04e28007e)
