oops. it works. I didn't ispect well the lists.
I added some functionality to oldParser:

- non-local returns
- arguments in slot initializers: (| add: arg With: something = (arg do:
something) |) now works
- binary methods slot initializers: (| + arg = ( arg addToMe: self) |)
now works
- resend:  "resend.unary","parentSlot.unary","blabla.+-** arg","res.key:
arg1 With: arg2",
     "SomeSlot.add: me".

currently I'm trying to add annotations parsing,
But I still don't know how to flatten the nested annotations. How can I
read the raw annotation string
(is there a primitive ?) to lear by examples ?

When finished I hope it will parse code generated by the transporter.
It uses a simple framework, just a couple of messages for string, list,
looping and boolean conditionals.
It could be easly used for bootstrapping from a minimal image. I belive
it is more compliant than my old parser since it was originally written
by the Self group, so it could be a starting poin for those projects
which aims to reimplement self (also porting to smalltalk it's straight
forward, a little too mechanical and boring but it's not big).

If someone is interested I can post the sources.
