)
static

Check for classes that accept 'objectForKey:' (or the other selectors that the migrator handles) but return their instances as 'id', resulting in the compiler resolving 'objectForKey:' as the method from NSDictionary.

When checking if we can convert to subscripting syntax, check whether the receiver is a result of a class method from a hardcoded list of such classes. In such a case return the specific class as the interface of the receiver.

FIXME: Remove this when these classes start using 'instancetype'.

static bool shouldNotRewriteImmediateMessageArgs ( const ObjCMessageExpr Msg,

Returns true if the immediate message arguments of Msg should not be rewritten because it will interfere with the rewrite of the parent message expression.

e.g.

[NSDictionary dictionaryWithObjects:
[NSArray arrayWithObjects:@"1", @"2", nil]
forKeys:[NSArray arrayWithObjects:@"A", @"B", nil]];

It will return true for this because we are going to rewrite this directly to a dictionary literal without any array literals.
