$variableName.someKeyPath? I can create an NSExpression for
$variableName, and I can create an NSExpression for someKeyPath, but I

The actual problem is that I'm trying to create an
Directly, yes. NSExpression stores a keypath as a single string, whereas
variables are store in their own kind of NSExpression object. When you replace
variables with new values, it's only looking for the certain kinds of
NSExpression objects to replace. Everything else stays the same.
