Properties? I don't see the connection at all. The instance variables
I'm accessing should be available only to the class itself. Otherwise
I could just use @public and access it the same way as below, but
allowing the function to be defined outside of the implementation.
I want to use an inline function in several places within a certain
method in the class, but still have access to instance variables, and
do so without passing them in as parameters since the function can
call external code which changes their values... it's a long story to
explain it thoroughly. :-)
Anyway, if the non-protected access is a known/common/public behavior
- great! I wish I knew about this ages ago.

properties, though, to learn when it's best to use properties.

Is the non-protected access of instance variables from functions
defined inside of @implementations documented anywhere? I'm
wondering if this some secret thing that I shouldn't use, or
something that's actually pretty common used?
@interface Foo : NSObject
{
int special;
}
- (void)print;
@end
@implementation Foo
static inline void dotheprint(Foo * self)
{
NSLog(@"%d", self->special); // If defined outside @imp it'd give
a compiler error
}
- (id)init;
{
[super init];
special = 5;
return self;
}
- (void)print;
{
dotheprint(self);
}
@end
