In Perl, a prefix dereferencer is denoted by the unary operator 'ref' followed by the variable name (e.g., ref($variable)). Prefix dereferencing allows you to access the value stored in a reference without first dereferencing it explicitly. This can be used with scalars, arrays, hashes, and other types of references. For example: my $array_ref = @my_array; print ref($array_ref); # prints 'ARRAY'
