name: builtins type: attrs constructorArgs: [mem.buildBindings(symbols, 128).finish()] renameInGlobalScope: false

Contains all the built-in functions and values.

Since built-in functions were added over time, testing for attributes in builtins can be used for graceful fallback on older Nix installations:

# if hasContext is not available, we assume `s` has a context
if builtins ? hasContext then builtins.hasContext s else true
