Well, that page seems to have grown into a flamefest. Anyway, the
statement is simply untrue. Lua 5.1 deals with this properly:

$ lua
Lua 5.1  Copyright (C) 1994-2006 Lua.org, PUC-Rio

1.2

1,2

I don't think that setting the numeric locale is a good idea in
general. But Lua's parser still works. It has an explicit
workaround for parsing floating-point numbers in non-standard
locales.
