For SIOD you can simply enter (define x 2) into a cell to give x the
value 2. Since Guile define doesn't return the value, you can use a kludge
like (begin (define x 2) x).

The namespaces are separate between interpreters, but not between buffers
or sheets. This is so variables can be shared between documents. To get a
new namespace, start another instance of the program.
