[fpc-pascal] Is it possible to redefine FreePascal types?

[Frank Church]

Lets say I am using some string variables, but I want to ensure that there
are no typing errors in some code I am using.
so I define newString as a new string type and declare a variable as
ANewString.

That way if I create a function such as functionUsingNewString(a:
newString) and I pass a plain string as a parameter to functionNewString
the compiler declares an error.

If c is string and b is newString and I do b := c the compiler should
generate an error unless I do b := newString(c);

Is this possible?
