[Boost-users] Idea for equation library

I've got an idea for a toolkit that uses boost::lambda to let you write 
'equations' on the fly in c++. For instance, consider the following 
pseudo-code:

==================
Equation e = x + y;
print e(x -> 5, y -> 10) // Prints 15
e = x - y
print e(x -> 5, y -> 10) // Prints -5
Equation d = eq(e) + z
print d(x -> 1, y -> 2, z -> 3) // Prints 2
==================

The idea is that you can encapsulate an algebraic function in a standalone 
'Equation' instance, and dynamically reassign that equation. It's built off 
of boost::lambda (of course), but it lets you name the variables rather than 
just refer to them with the standard placeholders (_1, _2, etc.). Is it 
worthwhile for me to post the toolkit code on this group?

Thanks,
