I agree that the format should be kept fairly simple, but
extendable-in-self seems like a good idea, and that means including the
most fundamental scripting constructs in the language itself.  I think
orthogonality would be a good thing, here (sorry Reiner), but if a
language has no underlying branching and looping there's almost no way to
stick those on top of it.  

I might propose these commands

//These 4 exist
//These don't yet

These should be enough to allow everything else we'd want to be
implemented in them, maybe in the same file that contains default

Yes, some of this looks a bit Lispy, but if we're staying with 
command [args...]
(and I think we should) then we're going to be Lispy no matter what.  The
complexity of the if and lambda commands will only be of interest to
extenders anyway -- the average user will only touch the first five

One additional thought: should we have some sort of arithmetic commands?

Just my US$0.02 (and my US$0.02 and my US$0.02...)
