Every AST node uses as_json to express the generic structure for
encoding itself. Expression aliases as_cbor to as_json by default and
then uses as_cbor in to_cbor (aliased as to_binary).
This design is because we need to override the encoding of Double for
CBOR, but want to keep the normal Float value for as_json in case that
is used directly (to avoid surprising the user).
If trying to import from IPFS, fallback to gateway
Update to latest dhall-lang
First pass at import resolution
Tests are long for good reasons
Builtins are part of the standard set
Make every Expression a ValueSemantics and use the known list of
attributes to map generically over any AST node.
Introduces a conditional, but removes boilerplate from every single
Internal flag to disable for acceptance tests from the standard (which
assume beta-only normalization in some cases). Otherwise, just always
alpha normalize as we go.
Update to latest binary format
Migrate to dhall-langv6.0.0
Use git-extras for `git root` in build
