Hi Thomas,

In general, a parser for such a simple language (i.e.

something else, but I don't think it's too problematic either (trust me,
2 years of compiler construction at university at least tought me that
;) ... and how to sleep without anybody noticing, but that's a different
story...)
Do we really need the "fork()" functionality? Surely we don't need
to
duplicate the entire volatile memory of the current shell in order to run
another - all we need to do is "run" another shell with the same Env and
local variables, right? We could send the daughter shell a message
containing the current variable settings.
Surely the use of "fork()" is an overkill for a shell?
