Except the fact that interface functions would have to be done
separately for each language, default rulesets have to use one of them,
some languages might require special handling - like keeping pointer to
script specific instance in main data etc. This is way too much work to
be #ifdefed.

I'm pushing guile because when working with integers (and freeciv could
work only on integers - all units/cities have integer ids) you do not
need to create any object - no need of referencing/dereferencing script
objects from C code. At least TCL have quite complicated integers I'm
afraid.

I'll try to write few routines to show how easy is creating/registering
interface funs with guile. If somebody can come with another language
same straighforward, I'll greet him with open hands.
