It's important to know that simple string concatenation is more efficient, and often much easier to read.
"method result - ${ \$obj->method }\n";
"method result - " . $obj->method . "\n";
An explicit join on space or
$" is more efficient than using
@{[]}.
"foo @{[ some_list() ]}.";
"foo ${\ join $", some_list() }";
"foo ${\ join ' ', some_list() }";
"foo " . join ' ', some_list();
Easiest to read imho is (s)
printf.
printf "method result - %s\n", $obj->method;
The idiom is also explained in perlfaq4's How do I expand function calls in a string?.
