Visual D expander bug

[Amex]

It seems this might be related to another bug.

When I hit F11 to step in to a function it does not step in. I 
can go to the function and put in a BP but I cannot step in to it.

This does not occur for most function.  It seems when the I can't 
expand a data structure related to the function I'm trying to 
enter, I also can't enter that function. It may be totally un 
related but something is off. How ever it is determined that a 
function is to be expanded or stepped in to has a bug.
