G'day proxie,

See the special variable $" (aka $LIST_SEPARATOR). Some examples: 

$ perl -le 'print @ARGV' foo1 foo2 foo3
foo1foo2foo3

$ perl -le 'print "@ARGV"' foo1 foo2 foo3
foo1 foo2 foo3

$ perl -le 'local $" = "~"; print @ARGV' foo1 foo2 foo3
foo1foo2foo3

$ perl -le 'local $" = "~"; print "@ARGV"' foo1 foo2 foo3
foo1~foo2~foo3

If you want to change the value of $", or indeed any special variable, you'd be well advised to use local. It might be considered overkill in little one-liner such as I have there, but it's a good habit to get into. In an actual script, I'd recommend doing it always.
