module Cop

# This cop checks for `raise` or `fail` statements which do not specify an
# explicit exception class. (This raises a `RuntimeError`. Some projects
# might prefer to use exception classes which more precisely identify the
# nature of the error.)
#
# @example
# @bad
# raise 'Error message here'
#
# @good
# raise ArgumentError, 'Error message here'
