I was addressing your point that:

> lambda functions in python have as much expressive power as any function.

There is no fundamental reason why Python doesn’t have let, and there is no fundamental reason to not be able to catch exceptions within a lambda. Python already fixed the unneeded print statement in its history so I think there is hope. (I don’t think js is relevant here; I was trying to explain why lispers or people who like Haskell may revisit their improved expressive environments).
