Well, that might work, but it makes the plugin code quite a bit more
complex.

Instead of adding complexity to the plugin API with symbol
prefixes, maybe we could support this by only allowing one plugin to be
loaded without G_MODULE_BIND_LOCAL. Would that work?

Good point ;-)

This would be the ideal way, but maybe it's not possible.

Another thing, could you check how other programs with plugins do
this? Pidgin has bindings for Perl and maybe some other
languages, do they use G_MODULE_BIND_LOCAL? (I'm not sure SciTE is a
good example, does it have a plugin interface?)
