Task

Create a function, compose,   whose two arguments   f   and   g,   are both functions with one argument.



The result of compose is to be a function of one argument, (lets call the argument   x),   which works like applying function    f    to the result of applying function    g    to    x.



Example

 compose(f, g) (x) = f(g(x))



Reference: Function composition

Hint: In some languages, implementing compose correctly requires creating a closure.




declare
  fun {Compose F G}
     fun {$ X}
        {F {G X}}
     end
  end
 
  SinAsin = {Compose Float.sin Float.asin}
in
  {Show {SinAsin 0.5}}
