Any idea why following won't work… enum permissions {

ban_members,
remove_members,
change_name,
change_perms,
delete_content,
invite_users,
send_content
};

std::bitset<sizeof(permissions)> user_perms;
user_perms.set(permissions::send_content);
?

sizeof returns the number of bytes for that type not the number of entries. Assuming your compiler chooses an 32 integral type, your bitset has only 4 bits

you can set the size to send_content+1, but it surely is not portable
