I never use shortcuts like `document.{name}`, myself, when there are methods
that explicitly select what I want. I just checked in Chromium and Firefox,
and neither of them just add elements to `document` by their `name`
attributes... maybe I misunderstood what you were talking about.

Either way, the method calls aren't that complex. They are also explicit in
what they do, and allow you to avoid naming conflicts with other properties
of `document` (and apparently, browser compatibility issues). They also
always return a collection of elements or a single element, depending on
which method is used, but independent of how many matches exist in the document.

Then that's a relevant requirement in itself. If you really want to support
as many browsers as possible, that limits the range of possible solutions.
The query selector methods, for example, do not exist natively on all
browsers. IMHO, you will probably have to define a cut-off point somewhere,
or you'll find yourself supporting horribly outdated and broken engines for
little actual benefit.

Dialogs (alert, confirm, prompt) usually don't trigger popup blockers, and
certainly not after they've been removed from the code :)
It's impossible to say what's going on here without looking at the code.
