Wonder if anyone could shed some light on this messaging construct:
The documentation says that messages appear btwn brackets  and that the msg target/object is on the left, whilst the msg itself (and any parameters) is on the right:
[msgTarget msg], e.g.,
[myArray insertObject:anObject atIndex:0]
OK, simple enough... but then they introduce the idea that it's convenient to nest msgs in lieu of the use of temporary variables--I'll take their word for it--so the above example becomes:
[[myAppObject theArray] insertObject:[myAppObject objectToInsert] atIndex:0]
In other words,
[myAppObject theArray] is a nested msg, one, and, two, 'theArray' is the 'message'. Well, to say I find this confusing is a bit of an understatement ... Maybe it's just me but 'theArray' doesn't evoke a message semantically or grammatically. What this looks like to a guy who knows Java is a type/class. In Java we do things like
Class objectInstance = new Class() ...
the bit to the left of the assignment operator is what this so-called nested message reminds me of ... with object and class/type positions switched of course. Anyway, any insight much appreciated.
