 In addition, I have been considering using SELF as the main programming
language for a transactional based persistent distributed object store which I
have been working on for some time. SELF appears to offer an efficient
type of language which makes its choice as a standard language attractive.
However, its lack of key features, such as transaction control, locking,
distribution, and persistence, means that I will have to fudge the language
semantics. Mind you, considering the complexity of SELF, the first version
of this is liable to be a cut-down version of the language (microSELF?).
Maybe I could use uPSELF (persistent)? In fact, I will go and write that one
down :-).

I have to agree that the other languages I have looked at (C/C++, Ada, etc)
would require similar semantic distortions to allow programming of my
store, but SELF has the advantage of being clean, new, and object-oriented
(truelly). Tasking would be nice though....
