lambdafy.js

//Good
function lambdafy( f )
{
  return function lambdafier() {
    var args = Array.prototype.slice.call(arguments);
    return function lambda(){
      f.apply( this , args );
    }
  }
}
//Evil, evil, evil
function λ( f )
{
  var name  = 'λ' + f.name, lambda;
  eval( 'lambda = function ' + name  + '() {var a = Array.prototype.slice.call(arguments);return function ' + f.name + '(){f.apply(this,a);}}');
  return lambda;
}

function hello( s ){ console.log(s) }

The evil version would not have been written if Function.name was a writeOnce property..
