4.13.3 Concatenation
Concatenation operator is ‘.’ (a dot). For example, if
$f
is ‘smith’, and $client_addr
is
‘10.10.1.1’, then:
| $f . "-" . $client_addr ⇒ "smith-10.10.1.1"
|
Any two adjacent literal strings are concatenated, producing a new
string, e.g.
| "GNU's" " not " "UNIX" ⇒ "GNU's not UNIX"
