@KevinvanderVelden I don't use any prefixes. In past several years never made such an error. Before I try to change something I should understand how it works and what I can break. Also I don't name local variables as the member ones. Maybe my discipline allows me to avoid such errors
@KevinvanderVelden can't imagine such situations. How can you treat a member variable as local. local variables can't exist without local declaration. Such thing isn't hard to notice.
