kaya binary package in Ubuntu Trusty arm64

 Kaya is a compiled statically typed (ie, types are checked at compile
 time) imperative programming language; unlike other such languages,
 however, types are inferred rather than declared - there is no need for
 type declarations of local variables. Kaya has "tagged union" data
 structures, a powerful feature more commonly found in functional
 languages such as OCaml and Haskell.
 .
 Kaya also has built-in abstractions for web application development,
 making it easy to write a CGI program without paying too much attention
 to low level details such as state management and form handling.
