Merge #3806
3806: lower bool literal value r=flodiebold a=JoshMcguigan Following up on #3805, this PR adds the literal value to `ast::LiteralKind` so when we lower we can use the actual value from the source code rather than the default value for the type. Ultimately I plan to use this for exhaustiveness checking in #3706. I didn't include this in the previous PR because I wasn't sure if it made sense to add this information to `ast::LiteralKind` or provide some other mechanism to get this from `ast::Literal`. For now I've only implemented this for boolean literals, but I think it could be easily extended to other types. A possible exception to this are string literals, since we may not want to clone around an owned string to hold onto in `ast::LiteralKind`, and it'd be nice to avoid adding a generic lifetime as well. Perhaps we won't ever care about the actual value of a string literal? Co-authored-by: Josh Mcguigan <[email protected]>
