module Ginny
# Used to generate a [module](https://ruby-doc.org/core-2.6.5/doc/syntax/modules_and_classes_rdoc.html).
#
# More accurately, wrap the `body` (first argument) with any following module definitions (additional arguments).
#
# @example
# Ginny.mod("puts('Hello World')", "Level1", "Level2")
# #=> module Level1
# module Level2
# puts('Hello World')
# end
# end
#
# @param body [String] Name of module namespaces.
# @param names [String,Array<String>] Name of module namespaces.
# @return [String]
