Hjelsberg's discussion takes a bit longer to absorb but
is well worth it.
Thanks. Off the top, some of what I like about Foxpro
comes back with the language integrated query. There
is a lot more, but I leave that to the language
junkies (of course, passing code as data is productive).
When I consider how much time and energy was devoted to
getting data separated from the code, it is a little
scary to see that much code dedicated to putting it back.
Still, I don't see new applications here. The reason
for the comparison to the days of markup prior to XML
when the users dominated the ecology. The closer one
gets to language design, the less one is thinking of
applying a language. A danger of integrating XML and
programming languages is forgetting that the application
user, the domain expert, may not wish to program given
it is an "inherently career limiting" skill.
So why exactly do we want to use XQuery or XLinq?
One reason, with my limited practical experience, that
comes to mind is that this is a lot like Foxpro in that
Foxpro, being a dedicated database programming language,
was a lot more productive than doing the same work in say,
Visual Basic. Having the queries in the procedural language
(once one mastered USE) was quite powerful and real rapid
prototyping.
