Summary: Type of array length is unspecified
Product: D
Version: 1.010
Platform: PC
URL: http://www.digitalmars.com/d/arrays.html
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: www.digitalmars.com
AssignedTo: bugzilla digitalmars.com
ReportedBy: jlquinn us.ibm.com
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.
