My reflexive reaction was 'ugh'.  My considered reaction is 'bravo'.
You have avoided the 'ghetto trap' that I think too many
mini-languages fall into by trying to be more or less turing-complete
with a proprietary syntax useless for any other task.  The Python
'humancode' fits pretty seamlessly into the declaration framework for
two reasons: the common use of significant indentation and the
semi-natural (versus chicken-scratch) look of Python.

If your declaration form requires overall noticeably fewer written
lines than the Python translation, then I probably could learn to like
it too.

I am curious: Will the CAPS marketers reveal or hide the fact that the
readable procedural sublanguage is a *real* language that CAPS users
can potentially use outside the CAPS box?
