What you want has nothing to do with the WithStatement, what you want is "inline variables", i.e a VariableDeclaration as an Expression.

Thanks for clearing that up! :) I am not a language expert so I do not know the terminology. Obviously I want something similar to what the for statement gives us - ability to initialise the variable and use it in inside the block.

the with block. Since with statement does not allow initialisation one would try:

As usual, I forgot to give an example of what I am actually asking for...

auto app = new Application();
with (auto win = new Window) { // currently not allowed
  setTitle("Example");
  setDefaultSize(200, 200);
  setChild(mainBox);
  app.addWindow(win);
}

Seems like a totally uncontroversial change to me. We already allow using a declaration in if, while, and switch statements; there's no reason with shouldn't work the same way.

Just to mention that there's an issue filed for this (in 2014 and duplicate in 2015):
