Uhuh, in my mind, it seemed to get off to a kind of shaky start, and never improved.
Rather than take the opportunity to design a more generic object model for widgets with a clear strategy in mind for mapping to a literal syntax, it seemed to me to have started by copy-pasting the entire API used by Morphic widgets, adding Spec in front of some of the class names, and call it a day.
Slap some {}'s around where appropriate, and you have a literal syntax!
The good news is, no-one in their right mind would willingly use the literal format as is, so changing it probably wouldn't cause too much of an uproar,
the bad new is, all the hard work involved in creating a sensical format, still remains.
It's also rather hard to make a good object model that you then later graft a literal format on top of...
For instance, with the use of blocks for everything, and the weird mix of symbols and method calls:
row newColumn: [ :col | col add: #topToolbar height: self toolbarHeight ]
I'd have no idea how to represent as a literal in an intuitive way.
