Many thanks for your detailed explanation, Hans.
I had no idea that the automatic conversion from string to number where
so dependent on the Lua version.

Well, I must confess that this is a new knowledge to me.
I thought that "[[ ]]" was the form to escape what I think it is the
escape character in Lua.
How I came to that assumption? Probably because I tried to add a raw
command to \ctxlua or inside a \startlua...\stoplua.

From this sample, I understand that "\" doesn’t need to be escaped
inside context(), does it?

I don’t need "[[ ]]", I only thought I needed them.
Many thanks for your help,
