Yes, that is indeed what I meant.

I wanted to benefit from being able to use multiple forms as in
lambda, but on second thought I guess this would conflict with `begin'
having a different meaning in macro templates than it does in function
bodies... I should prolly also rethink whether I didn't mean `(let ()
...)' in my code...

Thanks,
