> Really? I use this to validate config entries: entry, err = get_value(‘my_bool’). Entry is either true, false or nil if the user didn’t specify a value or gave an erroneous value. Why is that a bad idea?
I have encountered this frequently in Lua code. i.e. nil representing
"no value"
Also common is set_something(nil) meaning to use the default.
