Okay, but does that also mean my code--when licensed under the LGPL and
loaded by a proprietary program via libguile.so---may not call any Guile
code released under the GPL?

I am thinking specifically about the GNU Shepherd.

For context, my software aims to replace a common system facility.  The
current license is GPL, although the C piece that starts Guile via
libguile.so is available under the LGPL.  Likewise releasing the
remainder under the LGPL, however, logically implies that no interpreted
GPL code may be called by my software.  Is that right?

Kind regards
Felix
