Nope. Thanks. I fixed the typo, and claified the following text.

Did you consult the log? It should have listed something like -
Tue Jul 24 06:27:26 EDT 2001 [error] Error in evaluation of ==
expression. Both arguments must be of the same Class. Currently left =
class java.lang.Long, right = class java.lang.Integer. tal.vm [line 3,
column 16] (ASTEQNode)
This issue, namely numeric comparison, is something I will get to right
after we come to some conclusion about the separate instance version of
vel that is languishing on my local machine :)

To whom? Log messages, which I would argue are rather descriptive, go
to the log file under [error], so you could always grep for that to
avoid reading through all the goop.

It's *very* strict right now, and logs as such.

Cool. What does it do? (I love hearing about the app uses...)
