Nope - not funky.

Container syntax can be either a variable (with array indices or 
without), or an object chunk which has a notion of 'text' (i.e. button, 
field, image).

If it is a variable then the variable gets modified.

If it is an object chunk then the text of the object gets changed.

Variables are only treated as (potential) object chunks when being 
evaluated as a source, and only then if the thing operating on them 
expects an object. e.g. the blendLevel of tObject (property syntax only 
makes sense when targetting an object chunk, so the contents of tObject 
are parsed as a control chunk).

Indeed, if this wasn't the case then you wouldn't ever be able to change 
tObject in the following script:

   local tObject
   put the long id of field 1 into tObject

   -- If variable containers (targets) resolved as objects first:
   put "foo" into tObject -- this would set the text of the field to 
"foo"

Warmest Regards,

Mark.
