My take is that he's completely ignorant about Lua and that the
article is much more about "mobile apps in web browsers" not native
So, in making his case, he lumps all languages together and puts Lua
not allow you to control the GC, it precludes you from a critical
opportunity to overcome one of GC's limitations, which is suspending
it during critical points in the code.
My guess is that, if he deemed it relevant, he could do a simple test
and judge Lua against his points. I my experience and observation is
that A) He makes great points, B) Lua backs his points up and C) Lua
does the things that it needs to do in order to be a relatively
performant garbage collected dynamic language.
No fancy-new-GC required, as far as I can see.
