module Sorbet
# This cop disallows the usage of `checked(true)`. This usage could cause
# confusion; it could lead some people to believe that a method would be checked
# even if runtime checks have not been enabled on the class or globally.
# Additionally, in the event where checks are enabled, `checked(true)` would
# be redundant; only `checked(false)` or `soft` would change the behaviour.
#
# @example
#
# # bad
# sig { void.checked(true) }
#
# # good
# sig { void }
