D spec. i'm not really interested in C++ progress, and certainly not that much that i'll read any of it's specs. > The D specs I see are (from: http://dlang.org/function.html ): > > > > Auto Functions > > > > Auto functions have their return type inferred from any > > ReturnStatements in the function body. > > > > An auto function is declared without a return type.
