Hi, Thomas!

Sorry, this is not yet possible. The breakpoint facility uses hook directly
into the deepest type-checks for procedure application. This works nicely for
compiled code, but has the drawback that one can not access lexically bound
variables. In interpreted code, this might be posssible, but isn't implemented
yet. I will look into this, though (...but can't promise a quick solution).


cheers,
felix
