An alternative scheme for describing the block structure could be
useful in other cases, though. For example, if you wanted to support
putting snippets of Python in configuration files, or spreadsheet
cells.

There's no need to support the new scheme in .py files, so it seems to
me that this doesn't have to be done in the core language. All that's
needed is a variant of 'eval' which expects the alternate scheme, and
that could be prototyped just using text manipulation and the normal
'eval'.

If someone wrote a library for this and it proved popular, I expect it
would be considered for the standard library.
