LUA is FFOC

LUA is the toy language for those who enjoy the Forced Flushing Of L1/L2 Cache per operation. In fact, every operation causes several L2 cache misses during table look-ups, flushing both the L1 and L2 caches.

Enjoy your FFOC.

Lua's problem is that it uses hash tables for dispatching. This limits Lua to single dispatch in addition to making everything slow and rigid. You cant redefine `+` in Lua, as I do in my Lisp DSL

`+` a:Num b:Str -> "$a$b"
`+` a:Str b:Num -> "$a$b"

neither you can union two types

userFriendly? x:string? -> ye
userFriendly? x:picture? -> ye
