Summary: Macro-Script feature

Initial Comment:
Is it possible to create points and things from a guile
script (NOT a figure script that would be evaluated,
but rather a script that is created in an
already-existing figure?

I want to implement geometric inversion, so i want to
make new points/lines/circles based on already-existing
points/lines/circles. 

What would be the way to do that? (I'd rather not to
construction macros with loci for this)

What you are talking about look's like "macro-script" this
the kind of feature which can be added in the future of DrGeo. 

I undersand it as a mixt of the macro-constrction and the
DrGeo Scheme Figure (DSF) features. The DSF could be
immeditly  reused to implment the macro-script.

In short a macro-script could be a Scheme function (+ helper
functions as lambda functions) expecting as arguments
references toward other objects, then when evalulated the
macro-script will produce interesting side effect as the
creation of new objects in an existing figure. The
macro-script will be evaluate only once, as the
macro-construction.
