Is there a gravitational law for templating languages?
A templating language can emerge from the primordial ooze of mingled logic
and presentation, but there will always be an irresistable downward pull by
users to add features to undo the very reasons for the templating language's
existance.
Are there any that have reached a proverbial "escape velocity"?

for executing an instanceof check, then Use A Tool (tm). :)
public class InstanceOfTool {
public boolean isInstanceOf(Object a, String classname) {
Class cls = Class.forName(classname);
return cls.isInstance(a);
}
}
but of course, i don't recommend using such a tool for the reasons
James said. :)

What do you mean by escaping java? Do you mean displaying java code
literally (yes) or executing java in the page (yes for method calls, no for
everything else).

Man, I hope not, or one's typical velocity template will end up looking as
messy a typical JSP with its messy blend of presentation and business logic.
