Yes, the function is named CallbackConformanceArrayIn because it is a 
complicated expression and MIDL creates a callback function in C which 
implements the complex expression, and then stores an index to execute 
it at runtime.

Of course, this is a purely academic test file. Many of those problems 
would not be encountered or could be worked around with real IDL interfaces.

While you have demonstrated to me that the dceidl IDL compiler is very 
capable (and I did not doubt this), you still haven't demonstrated how 
this can benefit the Wine project. Yes, we can generate our own 
(probably) compatible client/server glue code (and this is ok for 
library-implemented functions like the registry or service functions), 
however we then lose focus on the applications for which we don't have 
source code for and depend on rpcrt4 being implemented. This is the most 
common use for Wine! If you have any ideas on how we can solve this, 
please let me know.
