# Checks for the usage of `require_dependency`.
#
# `require_dependency` is an obsolete method for Rails applications running in Zeitwerk mode.
# In Zeitwerk mode, the semantics should match Ruby's and no need to be defensive with load order,
# just refer to classes and modules normally.
# If the constant name is dynamic, camelize if needed, and constantize.
#
# Applications running in Zeitwerk mode should not use `require_dependency`.
#
# NOTE: This cop is disabled by default. Please enable it if you are using Zeitwerk mode.
#
# @example
# # bad
# require_dependency 'some_lib'
