I would like to suggest a method for defining code statement
covering. Some examp1es of a cover are as follows :-
  - try ... finally - this is defined in dotnet as a using
  - try ... (catch)+
  - cursor save and display others ... restore saved cursor

a possible syntax

  cover Hourglass(Application &app)
  {
    Cursor save = app.cursor;
    app.cursor = HOURGLASS_CURSOR;
    ~ code ~
    app.cursor = save;
  }

usage could be something like

  mixin(Hourglass(application))
  {
    ...
  }

You should re-post this on digitalmars.D.learn - this newsgroup is unused.
