Yes.

Basically yes. But only in double quoted strings.

You'll probably want to only change that for a little section of your
program so you would normally do something like:

{
local $";
$" = ":::";
 
print "@food";
}

So that $" is only effected in that small scope and returns to normal after
that block. The other way that might be easier to read is to do this:

print join(":::", @food);

Its a little more verbose but easier for non Perl coders to pick up and it
avoids the punctuation variables.

I had to code on a German keyboard at the LBW it's a night mare. Perl has
too many punctuations needs for heathen keyboards ;)

Next to the return key, between the right bracket and the shift key.
