As a non expert developer, I hate to see one-liners (using lambda expressions) when I am inspecting open source code.

So I would prefer they were not possible :)

While one-liners are almost always bad, the lack of non-crippled anonymous functions is the one thing that really bothers me about Python. They don't /have/ to be on one line; see Ruby's each blocks, for instance.
