The tilde of inequality operator is already painful to type on a french
keyboard, but the middot is not there at all. Wouldn't a single normal
dot do the job ?

a(1,"x"."y",2)
a(1,f"x"."y")

Or from an earlier mail:

myBigString = "The first part of the string "
            . "is followed by the the second "
            . "part of the string."

That's just a suggestion, I don't think the compile time string concat
feature is necessary. Since there are not that many unused syntax
constructs in Lua's syntax maybe we should spare them for more important
(future) features.
