Pattern: Use of send method when using mixin

Issue: -

Description

Checks for send, public_send, and __send__ methods when using mix-in.

include and prepend methods were private methods until Ruby 2.0, they were mixed-in via send method. This rule uses Ruby 2.1 or higher style that can be called by public methods. And extend method that was originally a public method is also targeted for style unification.

Examples

# bad
Foo.send(:include, Bar)
Foo.send(:prepend, Bar)
Foo.send(:extend, Bar)

# bad
Foo.public_send(:include, Bar)
Foo.public_send(:prepend, Bar)
Foo.public_send(:extend, Bar)

# bad
Foo.__send__(:include, Bar)
Foo.__send__(:prepend, Bar)
Foo.__send__(:extend, Bar)

# good
Foo.include Bar
Foo.prepend Bar
Foo.extend Bar
