I disagree. I do not want the expression processor to need
to know the state of the surrounding URI reference. We then
get into a discussion about what happens when {+foo}{?this}
is the template and foo := "hello?".
> The text about the '?' operator in 1.1 "Overview" isn't clear on this point. It says '?' is used for the first variable with a defined value in the expression. This is true for the specific example used in the overview, but not true in general (when a template might have some query parameters as literals).
In that case, the template should not be using the ? operator.
It should be using foo?literal=here&var={variable}
The description does have a problem with defaults, though.
