If opt are Lua strings and :match is the standard string.match,
perhaps what he meant, instead of \, was to use %, which is the escape
character for Lua patterns. However, since both "-" in the beginning
of a pattern and "-" in the end of a group carry no special meaning,
the correct code would probably be this:

 for i, opt in ipairs(arg) do
    local token = opt:match("-+([a-z-]+)")

Unless he means to match strings containing actual backslashes, then
the code would have to look like this:

 for i, opt in ipairs(arg) do
    local token = opt:match("\\%-+([a-z\\-]+)")
