R=ken OCL=16935 CL=16935
2008-10-10- implemented heuristic for composite literals starting with a type name:Robert Griesemer3-144/+116
if in a if, for, or switch header, must be parenthesized - implemented string concatenation - simplified a lot of code - added many more tests: can now parse all *.go files I got my hands on - printing output currently broken in some cases, use with -s (silent) option R=r OCL=16932 CL=16934

R=rsc DELTA=2 (0 added, 2 deleted, 0 changed) OCL=16927 CL=16927
2008-10-10- Fixed bug in spec: PrimaryExpr is too restrictive in most placesRobert Griesemer1-28/+57
(for instance *p was not allowed on the left side of "="). Changed to Expression everywhere (this is too liberal, UnaryExpr is probably good enough, but it seems funny, and we need to check semantically anyway). This matches 6g yacc. - Write expression syntac recursively to express evaluation order and precedence syntactically. - Organized open issues list, folded in stuff from todo.txt which is now obsolete.

2008-10-08- make optional semicolons explicit in grammar in all placesRobert Griesemer1-51/+53
