nill不是Lua的关键字

[Eroica-cpp]

nil 才是关键字，比如:

local myHero = Heroes.GetLocal()
if myHero == nil then ... end -- correct
if not myHero then ... end -- correct
if myHero == nill then ... end -- wrong
`
有意思的是，对于未声明的变量:

wtf == 1 -- false
wtf == nil -- true
wtf == nill -- true
wtf == nillonglongstring -- true
wtf == anotherWtf -- true
