I'm trying to do it using B::Utils. Looks like I'm wrong, since this code: 
#!/usr/bin/perl
my $s = sub { my $k = shift; return $k;};
use B::Utils qw( walkoptree_simple );
print walkoptree_simple( $s, { print } );

issues an error: Can't call method "isa" on unblessed reference looks like B::Utils does not work with coderefs. Any hint?
