I want discuss with you next idea:

This is UI definition:

style
   stage

     width:  100px
     height: 100px

     on: WM_LBUTTONDOWN
       {
         toggleClass( "selected" );
       }

   selected


body
   e stage

Here 2 sections: style, body.
Section "style" contains classes.
Section "body" contains tree of the elements.

classes like a CSS.
tree like a HTML DOM.



This is event handler:
     on: WM_LBUTTONDOWN
       {
         addClass( "selected" );
       }

( When element got event WM_LBUTTONDOWN, then executed DLang 
block. )

I want discuss, next
{
     addClass( "selected" );
}

It is a long code. I want simplify it in to short form.

How you think,
what is the best, readable, short, beauty form of the next 
expressions ?
addClass( "selected" );
delClass( "selected" );
hasClass( "selected" );
toggleClass( "selected" );



PS.
I think:
+selected // addClass( "selected" );
-selected // delClass( "selected" );
?selected // hasClass( "selected" );
~selected // toggleClass( "selected" );

And events will looks like this:
     on: WM_LBUTTONDOWN
         +selected
     on: WM_KEYDOWN VK_SPACE
         +selected
