Resolves #252

This check requires authors to initialize empty or zero builtin types
using the literal syntax (e.g., `{}` instead of `dict()`).

Authors may ignore this requirement for certain builtins using the
`--ignore` option.

Authors may also forbid calling `dict()` with keyword arguments
(`dict(a=1, b=2)`) using the `--no-allow-dict-kwargs` flag.

Fix error in README.md
