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.
