# typed: strict

# This module provides methods to define specialized attributes.
# Method stubs are generated by the {Tapioca::Compilers::Attrables} compiler.
# @note The compiler is fragile, and must be updated if the filename changes, if methods are added or removed,
#   or if a method's arity changes.
