Two-way embedding advice?

[John Sturdy]

Hi,

I'm working on a generic interpreted language embedding library,
Muesli (http://www.nongnu.org/muesli/) -- Multiple Utility, Evaluation
and Scripting Language Interface -- and I'm planning to put Syx in the
next batch of languages I'll embed in it. Any particular thoughts or
warnings on this?

The library provides a way for applications to call a scripting
language without hardwiring the choice of which language to use (the
user can choose at runtime) and it also puts some small extensions
into each language, including the ability to call all the other
languages.
