For the reason Dr Hawkins originally asked about ;)

There is no ambiguity if we have:

    1. 'the' IDENTIFIER 'of' ...
    2. 'the' STRING 'of' ...
    3. 'the' '(' EXPRESSION ')' 'of' ...

The key thing about making property syntax more flexible (e.g. multiple 
words - unquoted) is to enforce 'the' and 'of' - indeed, if you use a 
custom (non engine keyword) name of any kind then both are required so 
that's good :)

In any case, I got around to looking at it this morning and case (2) 
almost works already. Doing:

   set the "catness" of this stack to "very"

   put the customKeys of this stack

   put the "catness" of this stack

Results in a catness (no quotes) key in the stack's custom properties, 
but an execution error (source is not a container) when evaluating it.

Warmest Regards,

Mark.
