[Boost-users] [Proto] Building custom expression and new domain deduction not working

Here's an update on my last version. I have now added a new function building a custom expression node in a given domain. http://codepad.org/ddjFylti This code fails to compile under current trunk by saying that there is no proper operator+ to find. I guess it's because it can't see t and iota(0,8) to be in the same , compatible domain. Did I do something wrong ?
