This syntax on one line is interesting if we see "refinement" as a way 
to make more readable a too long line.

But I'm not sure wether this syntax is compatible with nesting different 
levels of refinement in a recursive way, as I did in an example.

Using "with" as an optional part of assignment seems to me rather 
restrictive, as too complex expressions may appear anywhere involving an 
expression, not only where expressions are assigned to a variable with "=".

Cheers,
