Is there a lot that needs to be specified? I imagine that the braces would
correspond to the special INDENT and DEDENT tokens in the grammar and
that's the bulk of the problem solved. The only remaining questions I can
think of are whether you would want to keep the colons that initiate
indented blocks and how to deal with ambiguity between the new blocks and
existing uses of braces like set displays. Anything else?
