To clarify: AFAICT, they work well – I use them intensively in my project. They do have a ‘limitation’: they don’t support things like $<foo>1, but you should not do that, except for midrule actions, for which Bison 3.1 will provide a solution. Move semantics is definitely a priority, for Bison 3.2. It is reasonable to expect this in October this year. _______________________________________________ help-bison@gnu.org https://lists.gnu.org/mailman/listinfo/help-bison
