I am looking for a way to display the code as well as the output when
running SML.
e.g.
fun f x = x * x;
f 4;
just displays
val it = 16: int
and I would like something like:
f 4 = 16
or similar to see what code was evaluated to get the 16
The only thing that occurs to me is to turn on "parsetree" debugging
with PolyML.Compiler.parsetree := true; The output is pretty-printed
into a form very similar to the original.

val it = f 4
val it = 16: int
