You haven't quoted any context to these two points, so I don't really 
know how to interpret them.

As far as point 1 goes, yes, I cautiously agree, but I don't understand 
your point, what you think that fact implies, or what relevance it has 
to the question of multi-statement lambda.

As for point 2, I think everybody agrees that having to worry about name 
clashes is a bad thing. That's why modern programming languages like 
Python have multiple mechanisms for avoid name clashes, e.g. functions, 
modules. To say nothing of the good ol' fashioned technique of using 
naming conventions to avoid nameclashes in the same scope. If somebody 
*routinely* and *frequently* finds themselves having to worry about 
clashes, they are probably doing something wrong.

But, I really don't understand your point. If you think this is relevant 
to the proposal, you should explain the connection, not just drop 
cryptic observations on the list.
