New Revision: 5859
URL: http://svn.gna.org/viewcvs/etoile?rev=5859&view=rev
Log:
Support block variables in Smalltalk. This uses the syntax described in the
EBNF definition on the Squeak site. This is quite ugly. Blocks with locals
look like this now:
[ :arg1 :arg2 || local1 local2 | statements ]
Note the double-bar between the arguments and the locals. With no arguments,
you'd write:
[| local1 local2 | statements ]
It appears that this double bar is needed to make the grammar unambiguous, but
it's still pretty ugly.
