Hmmm.. maybe, but..
One thing I like about the "with" tag is that it is scoped. Outside of
the tag block, the alias had no meaning, so their was no namespace
pollution. Your proposal puts the alias into the page's namespace for
all time (I guess it inherits through extended templates, too).
That's why I was having trouble coming up with something already: my
idea of perfect would be a tag has a way to specify both what it is
aliasing and what it's scope is. Without ugliness like {% with {% ... %}
as foo %}. Maybe a tag like "alias" should only live in its containing
"block" tag, if any.
It would also be nice if there was a way to unify variable lookup
aliasing and tag result aliasing, so that you don't have to think too
hard about which tag to use. Having both "with" and "alias" is not
ideal. It'll lead to lots of user blunders. Making something hard to use
incorrectly is a good goal to aim for.
This isn't something we have to solve overnight, so it's worth thinking
about a bit more, I feel. Those are the rough design ideas I've have
when mulling this over. Maybe I'm high, but probably not.
Regards,
Malcolm
