Just my 2c, I don't find lambda verbose at all, quite like it.
But I wish Python allowed for multi-line lambda functions... somehow.
Why? If you need to have a callback function that takes 2 to 5 lines of
code, then
(1) current lambda doesn't allow it,
(2) inline named function, defined earlier, is too verbose IMHO (code
style dictates it needs two blank lines, one before, one after, plus need
to have a name),
and also somewhat breaks the flow of reading code.
A multi-line lambda would be able to fill the gap, between too big for
single line lambda, but too small to justify its own def xxx().
Sorry, I don't have any concrete proposal, just a vague wish.
