It seems we're defining DSL in two different ways.
You can't write a DSL in Python because you can't change the syntax and
you don't have macros.
You can write a compiler in

So you can't make an internal DSL like this that uses Python's built-
in grammar. You'd have to hack the parser or settle for an external
preprocessor.
This time it is really hard for me but I begin accepting the fact that
I will have to build an external DSL. I experimented some weeks ago

O.K. Mark. Since you seem to accept the basic requirement to build an
*external* DSL I can provide some help. I'm the author of EasyExtend
( EE ) which is a system to build external DSLs for Python.

EE is very much work in progress and in the last

As far as I can tell, there are three different options:
- Embed a Python and DSL interpreter in the same executable.
- Write the DSL interpreter in
