What *ARE* you talking about. This makes no sense at all!

Euphoria does have a function type!

 function aaa()
  return 1
 end function

 a = routine_id("aaa")

 x = call_func(a,{})


The NAME of a function/procedure is passed as a parameter to routine_id()
and that returns an integer. The integer is an index into an internal table
of routines that the program knows about.
