[wp-hackers] Question about use of while in 2010 loop-page and loop-single

[Dion Hulse (dd32)]

You'd be right to however think, that "of course there's a post if
that template is loaded" as that assumption would be correct for the
template files you're looking at (basically anything other than
archive.php and index.php I believe).

TwentyTen/TwentyEleven however are also written to be (hopefully) of
use to new themers, IMHO It's much simpler to explain that "every page
has a loop" and make it consistently as such, not only does it help
new users get used to how to write a theme, but it also makes themes
consistently the same (Which is also a great help when you're
converting a Page template into an Archive template or similar..)
