I think it should be possible to correct the problems by replacing
their module and open primitives by a signature, a module and a link
primitive. While signatures don't have VM representations, everything
else can be compiled into structs and closures.
And of course you must support some kind of update protocol so that
the VM can re-compile and re-link parts of the system.
A low level module system and support for other module systems will
be trivial when Qscheme's VM and Goops are in the core, I think.
