This new proposal  looks like a very positive change on top of .
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.
