00:42 | <@simon`> | I've got an annotated AST that isn't annotated until after parsing. I handle the annotation info by having Maybe Info fields in various places. |
00:42 | <@simon`> | this means that after annotation, phases can safely assume that they're Just of something and never Nothing. but it isn't pretty. |
00:43 | <@simon`> | is the only alternative to have two AST datatypes, one that is always annotated and one that never is? |
00:43 | <@simon`> | I'm trying to think out of the box, but I can't come up with anything but template programming. |
00:43 | <@simon`> | maybe it isn't so bad. |

22:07 | <@simon`> | I wonder. normally one says that a grammar is LL(k), but the language it describes isn't necessarily. |
22:08 | <@simon`> | so I wonder, are there (deterministic) languages that cannot be described by any LR(1) parser? |
22:09 | <@simon`> | or rather, I've got an LR(2) grammar, and I wonder if I can make it LR(1). |
