[docs] [issue12704] Language Reference: Clarify behaviour of yield when generator is not resumed

Georg Brandl added the comment: Hmm, the yield statement is now basically the same as any expression statement -- just like a function call. The only reason it's a separate grammar symbol is that otherwise yield expressions would have to be parenthesized. Can the patch be updated to make this a bit clearer? Otherwise I like the approach of moving the info to the expressions page. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue12704> _______________________________________
