   i find one way for doing that...   
      
   (11) ->   
   w(h)==(p:=compiledFunction(eval(D(h(x),x),x,z),z)$MakeUnaryCompi   
   edFunction(Expression   
   INT,Float,Float);p(10))   
      
   Type: Void   
   (12) -> w(x+->x^2)   
      
      
      AXIOM will attempt to step through and interpret the code.   
      Compiling function %B with type Float -> Float   
      
      (12)  20.0   
      
   Type: Float   
   (13) -> w(x+->sin(x))   
      Compiling function %C with type Float -> Float   
      
      (13)  - 0.8390715290 7645245226
