[sf-perl] Prototypes, List::MoreUtils and subroutine references, OH MY!

I have a bunch of subs that are line for line identical, except that
they use a different one of List::MoreUtils qw(any all) [etc...].
No problem, I thought, I'll just create a generic version and pass in
a reference to the list function that I'd like to use.
Given something like this
my $any = \&any;
I've discovered that I need to call it passing in a code ref as the
first item in a list:
&$any( sub { ... }, @things );
where when I call any directly I pass in a block
any { ...} @things;
It seems that somehow the prototype magic doesn't travel along with
the code ref.
Is this the way it is or am I screwing something up and getting lucky?
