Removing the intermediate assignment to $name, broquaint’s code simplifies to:

use strict;

my $subref = \&{'dynamic'};
&$subref();

sub dynamic 
{
    print "Mmm, dynamic.\n";
}
[download]

which is explicitly documented as an exception to the normal behaviour of strict 'refs' (see strict):

There is one exception to this rule:

$bar = \&{'foo'};
&$bar;
[download]

is allowed so that goto &$AUTOLOAD would not break under stricture.

So, yes, this is canonical.

Hope that helps,
