No, I'm perefectly happy with both. I'm just trying to understand the
underlying reasons for people having trouble with one or the other, in
order to be better armed when the didactic need might arise.

One more question. Imagine that Python had something akin to Smalltalk
code blocks. Would something like

    map([x | x+1], seq)

be any better for you than

    map(lambda x:x+1, seq)
