OpenAxiom has two ways of handling Boot code:
(1) translate Boot to Lisp -- deprecated
(2) compile Boot to machine code directly -- for more specifically a
Lisp FASL
The preferred method is (2), as the system is minimizing lispisms and heavy
dependency on Lisp systems. At this moment, (1) is used only for building
the Boot translator itself, and is deprecated. Building the OpenAxiom
compiler and/or interpreter is done via (2).
My question was whether you wanted the ")read" command to just do (2), or
(2) + load the resulting FASL into the running system.
OpenAxiom applies more aggressive optimizations than other AXIOM systems.
This means that when you modify an existing function and it was inlined
into some of its callers, then recompiling the boot file might not
necessarily give you a consistent result. I don't know if this is a
concern for you. This consistency reason was the primary reason why
")read" for Boot script was removed at some point. I can put it back if
you are aware of the consistency problem -- meaning I won't be able to help
with consistency problems :-).
