There's been a lot of interest in and expanded version of the T5
expression language. I know T4 was equipped with ognl and people seem to
have liked that very much. I could very well be off base here, and there
may be a good reason for having chosen ognl before - but I'm curious -
if what is desired is a full expression language, why not tap into a
real scripting language? We could have a binding like 'script:' and
provide complete expressions that get passed to an interpreter. This
interpreter could even language agnostic (bsf?), as is jdk6's
ScriptEngine, and developers could use what they like (rhino, jython,
bsh, ...).
Perhaps this is a horrible idea, but if so I think it is transitive and
the actual bad idea is having an expression language at all. Its
certainly true that with such power one has enough rope to hang oneself,
at least from the view point of what a 'view' should be able to do.
Thoughts?
