+1

This new proposal [1] looks like a very positive change on top of [2].  
Simpler both to read and write.

One minor suggestion is to consider using a special character (eg $) 
rather than reserved keywords.  As I understand it the keywords are only 
interpreted when they exactly match the value of a key in a map, so it 
is already unlikely to be problematic.  However I think it would be more 
familiar and clear if we instead used the rule that any item (key or 
value) which _starts_ with a $ is interpreted specially.  What those 
rules are is TBD but you could for instance write functions -- as either 
`$get_param('xxx')` or `$get_param: xxx` -- as well as allow accessing a 
parameter directly `$xxx `.

Very excited to see where this goes.
