This is a fun topic.
Straight to the point sha. Can you add C# (or other code) you think shouldn't compile, but does? Lol!
Even better, can you tell us why the strange compositions we are about to witness are legal?

Mum's, at this point please hide your daughters. Bearded men be coming to play!

My first entry (really not a mystery):

class Trash
{
   int j
   ;
}

Second entry:

class Junk
{
    private void EyeTest()
    {{{{{{{{{{{{{{{{{{{{{{{{{
    }}}}}}}}}}}}}}}}}}}}}}}}}
}

Third entry:

class Trash
{
    private void EyeTest()
    {
        ;
        ; ; ;
        ; ; ; ; 
        ; ; ; ; ; ;
        ; ; ;
    }
}

Fourth entry:

class Junk
{
    private void EyeTest()
    {
        {;;}
    }
}

. . .And, mums its safe to bring your daughters out now. The man who takes good loving care of swiggly, wiggly, jigglies is about town!

class Beaf
{
    private void EyeTest()
    {
        ;;;;;    ;;;;;;  ;;;;;;;  ;;;;;;  ;; ;; 
        ;;  ;;   ;;      ;;   ;;  ;;      ;; ;; 
        ;;   ;   ;;      ;;   ;;  ;;      ;; ;; 
        ;;  ;;   ;;      ;;   ;;  ;;      ;; ;; 
        ;;;;;;;  ;;;;    ;;;;;;;  ;;;;    ;; ;; 
        ;;   ;;; ;;      ;;   ;;  ;;      ;; ;;

        ;;   ;;  ;;      ;;   ;;  ;;            
        ;;;;;;   ;;;;;;; ;;   ;;  ;;      ;; ;;
    }
}

Damn!

Ahahaaa , the conundrum indeed, here's on in JS:

var x=2, y=2
    
var Math_Funcs = {
    add:function(x, y){ return ": ----- )))) "; },
        multiply:function(x,y){ return "((((("; },
            reminder:function(x, y){ return /*x % y*/ ":-D" ;  }
};

alert(Math_Funcs.add(x,y));
alert(Math_Funcs.multiply(x,y));
alert(Math_Funcs.reminder(x,y));​

see what happens here: http://jsfiddle.net/gLmMm/2/

Oh no, but that was a fine looking piece of code?

Beaf, U too Gbaski, U have never betrayed my respect for You likewise omotodun. I doff my hat oooo.
