I've begun to see that lambda's are an attractive pole, indeed.  Yet,
lambdas returning None, and called only for side-effects, are against some
good taste.  I wonder which part of me will win over the other, but there
is some discomfort.  Python would help me much better at picking the best
solution, if only it was not offering lambdas :-).

As for lexical closures, you probably mean packaging widgets into classes?
This looks sterling to me!  But given you add:

I have the impression I did not understand what you meant by lexical
closures.
