Web version of C++

I was thinking of a new file format and language for browsers to support
(which will gradually render html, js, css, etc old style - like the middle
ages compared to today's world), file.homl + file.hos, Hyper
Object-orientated Markup Language + Hyper Object Stylesheet. Course I don't
expect the first release to come out until 2020 at latest if it does get
developed
