Marijn Haverbeke	6ba4eacddf	Make resolve recognize upvars ... Upvars are now marked with def_upvar throughout, not just when going through freevars::lookup_def. This makes things less error-prone. One thing to watch out for is that def_upvar is used in `for each` bodies too, when they refer to a local outside the body.	2011-09-01 16:32:44 +02:00
Marijn Haverbeke	2d1dec78e7	Move mutability checking into its own pass. ... Having it in the alias pass was slightly more efficient (finding expression roots has to be done in both passes), but further muddled up the already complex alias checker. Also factors out some duplication in the mutability-checking code.	2011-09-01 16:32:38 +02:00
