We assume meta-programming is less used in embedded environments. We have moved following methods: * Kernel module global_variables, local_variables, singleton_class, instance_variables, instance_variables_defined?, instance_variable_get, instance_variable_set, methods, private_methods, public_methods, protected_methods, singleton_methods, define_singleton_methods * Module class class_variables, class_variables_defined?, class_variable_get, class_variable_set, remove_class_variable, included_modules, instance_methods, remove_method, method_removed, constants * Module class methods constants, nesting Note: Following meta-programming methods are kept in the core: * Module class alias_method, undef_method, ancestors, const_defined?, const_get, const_set, remove_const, method_defined?, define_method * Toplevel object define_method `mruby-metaprog` gem is linked by default (specified in default.gembox). When it is removed, it will save 40KB (stripped:8KB) on x86-64 environment last time I measured.
