Hi guys, Currently, we are using the proto operator() overload and grammars to "group" expressions together. The result is one big expression that consists of several sub-expressions. An example can be found here: https://github.com/coolfluid/coolfluid3/blob/master/plugins/UFEM/src/UFEM/NavierStokes.cpp#L93
The problem with this approach is that for example the file above takes over 2GB of RAM to compile. I think this is due to the size of the expression (the group(...) call starting on line 93 is a single expression). I was wondering if it would be useful to find some other way to treat a group of expressions, maybe by using a fusion vector of expressions, or even using the new variadic templates of C++11? Could this have a significant impact in reducing the compiler memory usage? An extra complication is that the groups may be nested. In the example, there is a second sort of group inside the element_quadrature call.
