[boost] An interpreter: useful proposal?

Hi there, I'm developing an interpreter library support for a project, and I was wondering whether this could be of any help out there. Would it be useful? It provides some structured basic facilities, such as variables, l- and r-values, expressions, functions, subroutines, nested statements, but no object orientation yet. Please let me know whether it's worth the effort to share it here! (since there's still some work to be done :) ). Rgds, Daniel.
