But it does not need to do a function call. If getting the element size 
of a string is a pascal function it would be built-in.

Moreover I suppose (or suggest) that pos() is a built-in function that 
in fact can use decently optimized code.

Also a library function could use optimized pascal code that reads the 
element size, stores it in a variable and uses a pointer within the loop.

Of course a user function would just do s[x] and see some degradation.
