In fact,
(proc(x)=>print x)
cannot work but
(proc(x)=> print x;)
CAN work, for the same reason:
{ f x } // lazy expression
{ f x; } // lazy statement
There's no ambiguity here because of the semicolon. In fact
{ return x; }
is also an expression .. which is done with the 'trick' of checking
for a terminating 'return' statement .. and doesn't work with
{ if x do return y; done; }

Yeah but then you'd also want
module M inherits A { .. }
instead of
module M { inherit A; }
What we actually need is a 'generic grammar':
adjective name binder qualifiers = definition properties
or something, and then drive the parsing with a lexicon
and dictionary plus 'user defined syntax'.
