If I do something equivalent in C++ like:

void SetValue(int value)

I don't get any warnings. What is the reason for the warning in
Objective-C and no warning in C++?
Objective-C is a superset of C not C++ ;-)
Likely the compiler is simply not bothering to check if uses of the
lvar really do hide the ivar. File a defect if you want [1] but in
general you don't normally see much objective-c code accessing ivars
via struct references. In other words it is a case that isn't seen
much so their may not be much interest in changing it.
