Here are my comments (I also entered them on the wiki)
1) As we are all already aware I feel that the unsigned types in C are
useful. When problems occur it's because users convert between signed and
unsigned types without proper range checking. Since data access has this
range checking built in (after considerable effort on mine and Ralph's part
I will add) then conversion problems are possibly no longer an issue.
2) You have created interface classes for buffers, arrays, enumerated,
strings etc. All of these interfaces are already in data access. Was there a
good justification to create new ones? In any case, it seems that we should
the goal of using the same interfaces for each type of commonly used data.
3) These interfaces seem to require contiguous storage of random sized
blocks of characters. Doesn't this preclude use of fixed length buffer based
(free list based) memory allocation, and therefore almost guarantee
fragmentation of memory.

Subject: Fundamental Types document
Marty and I would appreciate feedback and comments on the following Wiki
document, which defines the fundamental types we want to provide and use
inside iocCore.
