shift/reduce conflicts: resolving by precedence about ply

[clime]

However I would really expect the shift rule to be preferred.

Or maybe shift-reduce conflict reported. The way it is caused some really puzzling syntax errors.

[clime]

Any progress here?

The precedence of a particular rule is determined by that of the right-most terminal, which in this example is probably the precedence of 'ID'. You probably need to write one of the rules as:

expr : ID WS ID %prec WS

Sorry I missed this issue before---I might have been on travel or away when it was first reported.

So I guess that my little hack at yacc.py:~2420:

   # clime: the original code commented out
   #sprec,slevel = Productions[st_actionp[a].number].prec
   #rprec,rlevel = Precedence.get(a,('right',0))
   rprec,rlevel = Productions[st_actionp[a].number].prec
   sprec,slevel = Precedence.get(a,('right',0))

is wrong. The variable assignment seemed somehow the opposite than it should be...
