First off fellow monk understand just what you are doing here.
Those dots you are referring to are the string concatenation operator. Each operator has a left hand side and a right hand side. I won't even start getting into precedence here since it reall y doesn't matter all that much.
my $thing = "Coca" . "Cola";
In the above example when $thing
is printed it will result in "CocaCola" being printed.
As far as the variables them selves consider this code block:
that will give you the same result as
which is the same as
my $left = shift @_;
my $right = shift @_;
but not necessarily the same as
# NEVER ASSUME!!!
my $right = pop @_;
my $left = pop @_;
# You may not get the result you are after!!
Clear as mud?
