           Summary: Type of array length is unspecified

        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

The data type of the array.length property is unspecified.  Is it int, uint, long, ulong?  C++ uses an unsigned value, but that makes writing loops like

for (int i=0; i < arr.length; i++)

not work without an explicit cast.  If you choose int, then you can't represent arrays larger than 2GB.

Whatever the choice is, the choice needs to be made explicit.

I was exploring D for an app that can have very large arrays, hence the question.

It's mentioned on the portability page ( http://www.digitalmars.com/d/portability.html ) that the length is of type size_t, but it would be good to have it on the arrays page as well.
