I hate to turn off strict. Why use strict if you are only going to turn it off ?

I usually do this: 

use strict;

sub foo { print "bar\n" }

my $func = "foo";
my $func_ref = \&{$func};

$func_ref->();

The reason this works is because the construct \&{$func} is exempt from the rule of strict references. It is as far as I know not documented in earlier perls, but code support for this construct has been in for a long time. It is documented in bleadperl IIRC

The construct is often used in AUTLOAD like this: 

sub AUTOLOAD {
    # get params and function
    # ...
    
    my $func_ref = \&{$func};
    goto &{$func_ref};
}
