Besides the excess q, you shouldn't use getDesugaredType for stuff  
like this.  Please use ->getAsFunctionType().  It will have the effect  
of desugaring where needed, and returns a pointer to the function type  
or null if the thing is not a function.

The reason for doing this is it is 1) more terse and 2) more standard  
across the sourcebase.  getDesugaredType should only be used for very  
specialized things.  ->isXXXType() and ->getAsXXXType() should be  
preferred instead.
