Dear Jeremy,
In what sense would closure conversion be correct for the untyped
lambda-calculus? Writing in an untyped language allows me to use pair/tuple
operations to access the closure environment, which was not previously
possible on the non-closure-converted calculus. If your untyped target
language (I think it should be made precise) contains a primitive
representation of closures (not just pairs), you can prevent environment
extraction, but then that corresponds to your third bullet of a target that
"supports (explicit) closure creation".
