Wrapping an expression in a lambda must not change the meaning of the
program. the following would need to be equivalent.
exp
lambda () {exp;}
If a return was required in a lambda then the following would not be equivalent
function() {
return 2;
return 1;
}
function() {
lambda() {return 2;}
return 1;
}
The first function would return 2 and the second would return 1.
That is my understanding anyway.
