This PR adds a
Macros
struct that can be used to extend the parser from external crates. This introduces a name conflict with the existing publicSexp
dependency. Since I don't believe that we need this dependency, I have removed it, which breaks all of the code that depends on theToSexp
trait, which is basically just resugaring. Since I do not see the value in resugaring I have removed it. However, I am open to having my mind changed on resugaring, in which case I will reimplementDisplay
for the affected structs without usingToSexp
.
