MESSAGES =

In many cases, you can use a node matcher for matching node pattern. See github.com/rubocop/rubocop-ast/blob/master/lib/rubocop/ast/node_pattern.rb

For example

{
  abort: 'Use `#raise` instead of `#abort`.',
  tap: 'Do not use `#tap`'
}.freeze
RESTRICT_ON_SEND =

‘on_send` will only be called if the method name is in this list

%i[abort tap].freeze
