YAML keeps surprising people in production. The Norway Problem (`NO` parsed as `False`). Silent duplicate key overwrites. The spec has 211 grammar productions. Most of that complexity exists to support features nobody wanted in a config file.
GYML is a strict subset of YAML. Valid GYML is always valid YAML. It keeps the block indentation syntax and pairs it with JSON's type semantics: one spelling for each type, no anchors, no aliases, no tags, duplicate keys are a hard error. From-scratch parser, no runtime dependencies, fully typed Python.
