With orif:
```lua
local flag = false
if i == 1 then
 flag = true
orif i == 2 then -- explicit fallthrough
 print(flag)
else -- default
 print "Unknown!"
end
```

Lua has elseif which is I think exactly the same:
local flag = false
if i == 1 then
 flag = true
elseif i == 2 then -- explicit fallthrough
 print(flag)
else -- default
 print "Unknown!"
end

No, elseif is totally different semantics, and elseif is exactly WHY I
think orif is a bad idea: elseif only fires if an earlier condition
wasn't true. orif looks syntactically like it ought to behave like
elseif, but it doesn't.

orif is the or operator combined with elseif.
It's similar to this (if Lua allowed this):
local flag = false
if i == 1 then
 flag = true
 goto next
elseif i == 2 then
 ::next::
 print(flag)
else
 print"Unknown!"
end
