This is a pretty far out question, but maybe someone could point me in
the right direction.
As I mentioned a few weeks back, I realized the ResourceLoader concept
doesn't fit my CMS, so I began to access the core API. I basically
completely rewrote my own RuntimeInstance (my class implements
RuntimeServices) and just about everything I need works... VTL is
found, parsed, rendered, context variables work, foreach directive,
etc...
One issue I have is with Macro arguments. The macro directive is
enabled, initialized, my vmfactory works, and I can create and use 0
argument macros just fine. It also works that if I define a 1
argument macro and use the macro with 2 arguments, it gives the
appropriate error that I passed the wrong number of arguments (I have
velocimacro.arguments.strict true).
However, when I create a macro with more than 0 arguments and use it
correctly, I get this stack trace I can't understand. I must be not
initializing something somehow, but it's so many levels removed, I'm
not quite sure what's going on.

The VTL in question is:
=======================================================
#macro (stuff $arg1)
Hello stuff $arg1
#end
#macro (foo)
Foooooo
#end
#foo() ## This works!
#stuff("foo") ## This gives the above stack trace
=======================================================
If anyone has any pointers on what this might be looking for, I would
greatly appreciate it.
