Fix lint issue from 501993eb

[akx]

Description

ESlint doesn't like polluting global namespaces like that.

Also, unless you really do need to rebind this, foo(...args) is the more modern idiom for foo.apply(null, args).

Heh, well, Lua was even worse – everything is global and you can also write to global names unless you declare them local.

Compounded by the fact that the global function to get a type from a variable is type, so you're one type = nil away from global disaster...
