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.
