This is an interesting post, it shows me that fitness plateau where
design of Python syntax lives is really small, you can't design
something just similar:

Living on a small fitness plateau isn't good, even if it's very high,
because it's evolutionary unstable :-(
Indentation-wise Haskell syntax seems one of the very few local maxima
that is close enough to the little fitness plateau where Python is.

Here is a somewhat longer comment:

Take it with a grain of salt and have much fun.
Python already has nested functions. So anything for which you really
need a lambda function can already be done. You just have to name
the function.
This isn't a popular feature, because in a language with no declarations
to determine scope, having too many nested scopes is confusing. But
it's there.
As for Python indentation, that seems to work reasonably well. The only
complaint I have there is that mixing tabs and spaces for indentation
should be detected and treated as a syntax error. (Whether to use
tabs or spaces is a religious argument, but mixing them is clearly
wrong, and results in non-visible bugs. CPython should enforce
that.)
