calc-mode's calc-embedded broken

[ChrisK]

This is from "Chris Kuklewicz" <address@hidden>

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing 
list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In calc-embedded mode in Emacs-21 I can assign a local variable
and refer to it in the same buffer.

This is completely broken in Emacs-22, as it ignores the variable
assignment.

What it should look like:
foo := 1
foo + 1 => 2

What it does look like:
foo := 1
foo + 1 => foo + 1

This means that calc-embed mode is quote broken.

This is broken for calc-mode 2.02f under Emacs-22 CVS pulled today, 
2005-03-09.
It is not broken for the calc-mode 2.02f under Emacs-21.
(I got the version 2.02f from lisp/calc/README in both cases)

But these calc-mode's have elisp files that differ substantially since 
calc-mode
seems to be becoming part of core Emacs-22.
