Sorry, I can't help there.

Yes, I talking about the values too.

I dislike inherited values becuase you don't always know when threads will be
created, e.g. a library might start a background maintenance thread when you
call it for the first time.  Inheriting values from the dynamic environment
where that happens is undesirable IMHO.

Moreover, inheriting the value of any mutable object (e.g. readtable, pprint
dispatch table) means sharing it between threads, which is little better than
sharing the global value.
