A code reference can be assigned to a local or lexical (my) variable. Named subs are always package global.

Here is a sub which takes a list of code references and returns a coderef to a function which executes them in order on @_.

# Usage: my $code = codestick( \&foo, \&bar, \&baz);
# Call with $code->(LIST);
sub codestick {
    my @subs = @_;
    sub { &$_ for @subs; }
}

That's not necessarily a design you'd want, but it illustrates the syntax. The weaknesses include implied strong coupling between subs you'd list in the codestick call through their need to cooperate over @_.
