Wow! Thank! I mass.
I was mean comparation:
Analog C-code with macros:
     #define TPL(M,D,CODE) if ( state & M && diraction == D ) CODE;
example code
     TPL( OPEN, OUT,
       {
         delete AppsWindow
         state &= !OPEN
       }
     )

It possible in D ?
How pass code block to template ?
How to solve this problem ?


Sorry. How to delete thread ?
