new A().b() currently requires extra brackets/parentheses

Hi Ben,

you could use factory functions:

class A {}

A a() { return new A();}

(and appropriate overloads for the different A constructors, of
course). Which would give you:

dialogue=guiDialogue([
        guiLabel(titleText).setLayoutHint(GuiLayoutHint.TOP),
        fileNameInput.setLayoutHint(GuiLayoutHint.TOP),
        currentDirectoryLabel.setLayoutHint(GuiLayoutHint.TOP),
        confirmButton,
        guiButton("Cancel", {dialogue=null;}),
]);

For the delegate at the end, I *guess* (but I'm not certain) that just
using { ... } will work. It's a void delegate().


Then:
