Pattern: Nested method definition
Issue: -
This rule checks for nested method definitions.
# bad
# `bar` definition actually produces methods in the same scope
# as the outer `foo` method. Furthermore, the `bar` method
# will be redefined every time `foo` is invoked.
def foo
def bar
end
end# good
def foo
bar = -> { puts 'hello' }
bar.call
end# good
def foo
self.class_eval do
def bar
end
end
end
def foo
self.module_exec do
def bar
end
end
end# good
def foo
class << self
def bar
end
end
end
