[pygccxml-development] recursive import trick

[Allen B. <al...@vr...>]

I was just trying to trace through the code in declarations.scopdef and 
I ran across a comment in declrations._init_.py about needing to use a 
rather interesting set of dictionaries in scopdef_t to inject some types 
for use when looking up matchers.

There is a comment on line 223 saying this is to prevent recursive 
imports, but it doesn't go into details about what imports cause this 
issue.  Could anyone shed some light on this?
