Description

There're times we use some lagacy code, like some libraries, which write directly to global name space.

We do also prefer it to not use global variable, but simply find it troublesome when we have to either quit using existing lib or modify the lib source by hand.

For some reason rawset(_G, 'yaml', false) trick does not always work, we need an official support to disable the warning.

Research direction

Start by locating the implementation of the _G write guard warning and the handling of rawset(_G, 'yaml', false). Determine how an official way to disable the warning should be exposed without modifying legacy libraries. Done means the supported option reliably suppresses the warning when requested.
