sure, i do this all the time (and i'm sure many others).

also, since in Lua functions are really anonymous (unlike Python), it
doesn't pollute any namespace (the table itself is the namespace)


-- easy to write...
local dispatch = {
   start = function (x) .... end,
   continue = function (x) ..... end,
.....
}

dispatch[state](x)             -- and easy to call!
