More useful to_s for AST nodes
Facility to flatten let blocks
Add new useful facilities to Function
as_dhall for Proc
Cannot actually serialize this, but can be useful for passing functions
in to Dhall functions, etc.
Update to latest dhall-lang
Split Union and Enum
Stop putting special case conditionals for Union#value.nil? everywhere
and just split the classes.
Caches implemented in this commit:
StandardFileCache - cache conforming to dhall-lang
RamCache - stores in a hash, meant for single-load caching
NoCache - when you want to be sure
Sets timeouts in HTTP readers, checks for deadline exceeded before each
resolution step, and uses Timeout::timeout for pure-ruby computations.
Dhall::Text is obviously the Text builtin, not the Double one.
Do not load if already loaded
In case the resolver has some values already
Update handling of builtins
Always parse to a special value and not to variables.
Normalize text concat as interpolation
Parse expression from ENV var import
Instead of the path-only support from before.
Add grab-bag of useful utils onto expressions
Optional#value is not what we want here
Run all dhal-lang typecheck tests
Run all dhall-lang tests for normalization
Environment variable failure can fallback
