Pattern: Missing use of keyword argument

Issue: -

Description

This rule checks for places where keyword arguments can be used instead of boolean arguments when defining methods.

Examples

# bad
def some_method(bar = false)
  puts bar
end

# bad - common hack before keyword args were introduced
def some_method(options = {})
  bar = options.fetch(:bar, false)
  puts bar
end

# good
def some_method(bar: false)
  puts bar
end
