On eval and its substitution of globals

[Paddy]

Thanks Kent for your reply.
I had to do as you suggest but I was thinking either it was a kludge,
and there should be a 'deep' substitution of globals, or that there was
a good reason for it to work as it does and some magician would tell
me.
Oh, the third reason could be that it was first implimented that way
and no-one has submitted a patch of course.

Could someone clue me in?

Ta,  Paddy.
