If x is a scalar value, the function returns a strictly negative integer related to the type of the argument (that is, two scalar values of the same type gives the same result).

If x is a map or a tab, the function returns the number of elements in its argument (which is a positive integer).

If it is a nim, it returns the number of breakpoints of the nim (which is not the dimension of the nim). Note that a nim with zero breakpoints is the result of a wrong definition.
