First, x[0,1] can't be resolved (unlike tab_x[0,1]).

For the rest, I'd guess you must add the proper replacemen "method" for
`own_lang'. Is this the case?

I mean: depending on the Babel language, variables must or must not be
prefixed by a $ sign to be replaced in the code block. For example, in Emacs
Lisp, you won't prefix vars with $.

Maybe have a look at `sh' or `sql' Babel languages for inspiration.

Best regards,
