At least, I'm not alone here. :)

I remember that while converting WebKit objc interfaces to C# with 
monomac parser, I've noticed that some properties in objc were marked as 
'copy' or 'retain'.  The parser never used these attributes in any way 
AFAIK.  Could it be that some of these missing attributes are biting us 
at run time in such a weird way?

I've grepped through monomac & maccore sources but found only a few 
places where ArgumentSemantic.Retain attribute was used, so I guess it's 
not very popular.  Do such exported properties have any runtime 
difference as opposed to the plain ones, not marked with ArgumentSemantic.*?
