But that's just my current mental model, which history has shown

Doesn't feel terribly clean to me though.  If we stick with the +
twigil always meaning at least one CALLER::, then clarity might be
better served by
    env $result := $+result // 1;

assuming that $+result merely returns undef in the outermost env context.

Wouldn't that bind $result to a constant at the outermost scope -- and 
therefore to that same constant in all inner scopes? If so, then later 
attempts to assign $result would be an error.
