"[1,2]".to!(myint[]) or whatever variant fails

And preempting the argument, "toString of arrays produces whitespace while conv.to has been designed to not take white of int cause such and such bug", you cant exactly add a "to(T)(string s) if(isArray!T)" yourself as it will cause scoping issues; if you change "to_" to "to" in the file I provided it produces errors of otherwise working concept code
