Absolutely the issue is uplevel addressing. nested procedures without
uplevel addressing are a rather small feature, they provide a bit of
namespace protection, which can be provided by other means.
The context of the original remark was to do with threaded programs, where
nested procedures and uplevel addressing are an enormous help in writing
thread safe code. Have a look back at the start of the thread, and reread
my comments on the structure of printf for an example.
