This was not my question i.e. if I can migrate between JS/PHP/Java on the
one hand and C on the other hand -
My question was, if I can implement in C, a "VM" that executes a compiled
version of the code, within some kind of interpreter, so I easily can do
completely safe Scheme code execution within that VM -
I.e. I can followup memory allocation and which globals/what environment I
allow the "guest" code to run.
Perhaps this could be as simple as getting the JS/PHP/Java-format GVM code
and implementing some kind of interpreter/VM for it?
