class String
# Constantize tries to find a declared constant with the name specified
# in the string. It raises a NameError when the name is not in CamelCase
# or is not initialized.
#
# @example
# "Module".constantize #=> Module
# "Class".constantize #=> Class
#
# This is the extlib version of String#constantize, which has different
# behavior wrt using lexical context: see active_support/inflector/methods.rb
