Isn't that what you should be doing anyway?

I mean, this is the documentation I found on using "#" with select, anyway" of wowpedia.

local num = select('#', ...) -- Returns the number of arguments in the ellipsis.

You have a table there instead of a vararg. The number of arguments there in that case would be one.

I always had an aversion to using select() anyway. I would do that this way:

local events = {
     "EVENT_ONE",
     "EVENT_TWO",
     "EVENT_THREE"
}
 
for k,v in pairs(events) do
     myFrame:RegisterEvent(v)
end
