I would expect blocks to be blocks, accepting also statements and sharing the scope with the surrounding code, not having early-binding semantics.

Honestly, given the introduction of generator exprs, a substitute expression for lambda with early-binding semantics makes sense. Personally I can see it also as meaningful wrt the statemenent/expression dichotomy in python, and we would have early-binding as a general rule for "expressions". But again I think that a block-like syntax should be used, if at all, for real blocks.

Thanks -- that all makes sense.
