Hi, what is the easiest way to convert an mpl::sequence to an std::sequence? I'm using such conversions a lot when unit-testing meta-code. I just wrote two versions of algorithms, a compile-time and the runtime one, and then compare their outputs. I recall hearing something about mpl::for_each having defined an operator () for runtime purposes, but the details don't seem to be documented anywhere. I came up with the attached code, of which the "to_compile_time" might actually be of general interest. It's a function that converts a runtime integer to a compile time integer. Code-generation-wise it's a horror and it could be more generic, but it gets the job done for me. I'd like to hear if there are more elegant solutions for this though, as it seems like too much code. Thanks, Jaap Suter
