Just to get ahead of things, I'd like to avoid discussions that reduce
down to the merits of a static typing vs. weak typing vs.... Not that I
thought you were doing this Ed, just making a blanket statement early
in. You know, there's more than a few former Smalltalk programmers here
(sniff) and I'd love to live in a world where our Java doesn't require
extensive testing. At this point, everyone's picked sides, the
arguments have been played out, and beliefs border on the religious
without much chance of converting someone.
I'm completely with you in the value of first class metadata support.
What's clear is that we'll need to drive the model from languages which
run the gammut of typing. Your response below Ed suggests that EMF is
flexible in this regard, right? But is that just in the definition of
the model or in consumption too? How do we say access a strongly typed
EMF model from a language like Javascript?
Are we talking about JavaScript in the browser or JavaScript as part of
the JVM?
If we talk about Scripting inside the VM, they have access to all
Java-Types you give it access to via imports or using fully qualified
names.
So far I only used Groovy where you could simply pass this script to the
engine and it knows what to do.

I haven't used Rhino but I think it works a bit different because Eric
is somehow wrapping it in a ScritableObject where the conversion has to
happen in the put-method in case the given parameter doesn't match the
one coming from the client.
