T/type keyword



T <type name>
   String s // instance variable
   . String ps // private instance variable [rationale: dot is used for hidden files and folders in Unix]
   F (s) // constructor
      .s = s
   F get_s_len() // member function (method)
      R .s.len

[Because 
T
and 
type
are keywords in 11l, use can use 
Ty
and 
type_name
instead.]
