Of course it does. Using uint or int would just be
inconsistent. My opinion is that the compiler should treat
size_t as a different type from both uint and ulong, so it can
warn about portability issues when switching between 32-bit
and 64-bit. I know some who say "But it is easy with dmd to
test both 32-bit and 64-bit", but in reality we see these
size_t doesn't match uint bugs way too often.

Anyway did you report a bug to dfl or did you just want to
make another point about how int is better for lengths?
(No, it is not going to happen. :) )
