In the case of this signature, the text that you changed deliberately is
the actual Perl code that gets executed. Perl is a dynamic language
which means that many information (including the code itself which is to
be executed) can be provided and manipulated at runtime:
$string = 'print "hello world\n"';
eval($string);
is a valid Perl program where the actual action happens in the eval().
With this it's the same as with the signature: Make some changes to
$string and the program might no longer work.
But don't focus on that yet. First make yourself comfortable and
familiar with Perl and programming in general before you tackle things
like dynamic code generation. You've found the right spot with this list
to get the necessary assistance on this way.
