Nothing wrong with passing code refs at all. It is common. Some folks
prefer to pass *named* subroutines instead of anoymous ones. Eg:

$thing->method(sub { "whatever" });

might turn into

sub whatever {
   "whatever";
}

$thing->method(\&whatever);

this style will produce more comprehensible and easy to debug error
messages. But tons of folks dont bother.

Good luck.
