This is what peak performance looks like:

  let
    eval  = expr: import ( builtins.toFile "__EXPR" expr );
    xeval = expr:
        let rsl = toString ( eval expr );
            elen = builtins.stringLength expr;
            splitC = if ( 60 < elen ) then "\n    " else "  ";
        in "( ${expr} )  ==>${splitC}${rsl}";
  in xeval ''let noun = "debuggers"; adj = "bloat"; in noun + " are " + adj''



( let noun = "debuggers"; adj = "bloat"; in noun + " are " + adj )  ==>
    debuggers are bloat

That’s all, thanks for reading.

Bonus points to whoever adds seq and toXML for maximum effect.
