If I get a vote, +1/2 from me.
My vote isn't +1 because I'd rather see a syntactic restriction removed:
make the inside of a `begin' an internal definition context. Then the
change would happen in every similar macro at once.
Also, I could do
(if <condition>
(begin (define ...) ...)
...)
instead of the current (and very ugly)
(if <condition>
(let ()
(define ...) ...)
...)
which I've been doing a lot more now that I can mix internal definitions
and expressions.
Would it break much? Would we end up needing a `#%plain-begin' and
changing macros that search inner syntax for `begin'?

+1,
In macro definitions that produce code with bodies, I almost by routine
write (let () etc ...)
There may be a problem including the bodies of begin forms, for they may be
lifted out.

+1.
I routinely wrap cond/when in let () for just that purpose.
