Respect final as literals

[milo]

An idea is that only final followed by class or function is the keyword to remove. If followed by = (constant assigning value) or ( (method signature) it is a literal.

Also needs to consider formats like final static function or final public function. 👍

Have you considered using TOKEN_PARSE flag of token_get_all (available in PHP 7+)? I've never used this, but it looks like it may help.

@JanTvrdik Neat, didn't know that one! 👌 That may work, if that also applies to Foo::FINAL.

@Majkl578 Actually final starts caching, no matter of other keywords order.
@JanTvrdik Good idea! I'll check it.

@JanTvrdik You are right 😄
