I believe so too. For my purposes it's sufficient that I can refer from
any cell in Clang runtime (especially the activation stack) and from any
cell in a Clang program. So restricting start cells like this shouldn't
be a problem. The important thing is that any cell can be referred to
as many times as necessary, transparently.

It depends. After I get Thales Clang going we'll know better. It's not
I believe I could design the next Clang (Heraclitus Clang, after
"the obscure" Heraclitus from Ephesus, ~500 BC) as a systems language
aiming for efficient compilation.
Are we targeting the Java machine or some real machine?
