Two constructors in
LoadingFailure
represented failures that are not necessarily limited to failures that can only happen when loading an asset, namely, parsing failures and typechecking failures. For example, we could fail to parse or typecheck a term entered at the REPL, which has nothing to do with loading an asset. This PR:SystemFailure
.SystemFailure
into aLoadingFailure
(via the newGeneral
constructor; name bikeshedding welcome)CustomMessage
constructor fromLoadingFailure
since now that can be achieved viaGeneral . CustomFailure
.This is a preliminary refactoring moving towards a PR for #495.
