Thanks for the discussion! I'll try implementing it and see if it's faster. It might be the case that with mutable strings in Ruby it's only faster on really big templates? I think pretty much everything required is in place and it's just a case of connecting stuff together with an option to use an array, except for implementing writev for CRuby which also shouldn't be too hard. It can even be an extension for now.
