shuujii / mruby-shared-empty-iv_tbl.md
Created February 3, 2021 12:45

An iv_tbl is not shared when a class includes or prepends an empty module

Example

If a class includes or prepends an anonymous and empty module and then a constant or class variable is added to the module, they cannot be referenced from the class.

m = Module.new
#M = m = Module.new
C = Class.new{include m}
