Here I have
$ sed -n '175p' boost/boost/any.hpp
throw_exception(bad_any_cast());
I think that you should 'cvs -q up boost' and the problem will be
resolved.

Thanks for doing that Lars. I see that the change has been committed
and have noted the comment about including the appropriate header.
I'll commit the changes to the lyx tree.

As discussed.
Lars, could I get you to apply this/contact the boost list as you see
fit?
I note that there are a total of 34 throws in the boost libs

I would love to, but that would mean storing a pointer to a
boost::function.

the thing stateless before because I needed the front(), back() member
functions to have the same signature.
Now that you have shown me how to use boost::any that could change.

What's the drawback?
I.e. which of the currently supported compilers don't 'do' exceptions?
[I am fine with them btw.]

Attached is a simple sample showing how I could use boost::any to implement
the transformation stuff in InsetExternal.
I think it results in very elegant code, but the killer is the try,catch
block. The block is needed, so I guess that this means I cannot use the
appropach within lyx?
