This looks better than the current design. When porting code to D from other languages you need to add something like a @globals attribute, but this seems an acceptable price to pay. Time ago I have suggested an attribute to regulate the usage of global (outer) names inside functions; the weak purity seems an "extreme" version of it. Bye, bearophile
