Dear list, some updates about my problem.
I eventually decided to do the things The Good Way.
Adding a shortcut to EmuLisp was a fun hack, almost a joke, but not a
good idea as:
1) It was not EmuLisp anymore.
2) I may need this export functionality with other platforms (read

But this IS the idea I'm trying to explain!!!
The problem was to also redefine transient symbols, dynamically.

Why not redefine function Afficher?
Have one file in which Afficher has the original functionality, and
another file were it instead produces this bockly XML ?
Then you write your simple program in a third file, and depending on which
of the other two files you (load), it runs or it produces XML.

Suppose you embed a DSL in Picolisp,

Hi Christophe,

>>> changed to some XML containing the string "hello".
in other words, you want to use the transient symbol "hello" as a
variable? What is preventing you? It's often done in PicoLisp.

I had no problem with functions (I used a simple «d

Quite the same, except that we don't have a list of all messages to
translate. Any transient, even an unexpected one, should
«spontaneously» have

I'm not sure I understand the question.
The value of symbols (not only transients) is the CDR of the cell
representing the symbol. The evaluator of the interpreter fetc
