I tend to disagree, I do not know about Lua, but  for me Ruby's methods are
pretty much first class
<code>
class A
    def a; puts "#{self} =3D=3D 42"; end
end
class B < A
    define_method :another_a, A.instance_method(:a)
end
AA =3D Class.new A

A.new.a
A.instance_method(:a).bind(AA.new).call
B.new.another_a
</code>

I do not know what can be done more in Lua and JavaScript but would be happ=
y
to  know.
