While wrapping parts of OpenSubdiv for Rust [1] I noticed the C++ API was littered with uses of int for indexing/lengths (both are always positive) of geometry buffers.
So I opened a ticket with Pixar [2].
Some of the same strange arguments were brought forward (incl. the Google style guide BS).
I wrote a longish reply [3] that mentions two comments [4,5] from an ill-guided article promoting use of signed in C++.
I closed the ticket in the end because I felt that if people really believe there are good reasons for signed in the cases at hand they haven't grokked the problem sufficiently – trying to convince them otherwise would not be a good use of my time.
