Ah, sorry, my bad.
Now I remember preciser what was my formatting idea originally.
That would make things clearer indeed - the separator would be TAB
character only. (I wrote tabs or spaces in proposal).
The root of the idea was finding a cleaner way for defining tables and
data plus some experiments with nesting syntax, etc.
Back then I did not think much about supportin expressions
inside elements, so this important issue slipped through.

So with the TAB separator, just think of replacement TAB->comma,
this should support all Python expressions automatically.
At least seems to me so, but if I am delusional - please correct me.

Of course the reality is still, that sadly, most editors cannot handle tabulaton
adequately. But I am a believer and hope for better future.
(Heck, people building space ships and what not, so maybe tabulation
in code editors comes next?)
