Re: [NASL2] Auto-conversion with + and -

A way to do it could be to force the types of the arguments with int()
or string()
Unfortunately, string() does more than converting its arguments to
ASCII: it interprets escape sequences in "impure strings".

But many scripts will be broken then.
string() could be used to concatenate strings, with the problem with
"impure" string. Maybe we just add a "strcat" function ?
(this is simpler than adding a Perl-like dot operator)

This can be done with int("123") + int("7")

Here is my proposal, for the moment: I add a BIG warning when + or -
arguments are converted. We wait for a while, and if all the current
scripts are OK, we remove the "auto conversion" and returns an error.
