Update: Fixed argument-modification error, thanks to tilly for pointing that out.

Did someone say golf?

sub chain{(*f,*_)=@_;@_=&$_ for@f;@_}

Of course you probably want strict compliant and it is bad style to modify your arguments in place. In which case it is probably better to make that:

sub chain{my($f,$a)=@_;$a=[&$_(@$a)]for@$f;@$a}

which is still reasonable...

use strict;

# a ref to a few subrefs to go, performing as secified
# in that they take an array, do someting and return an array
my $agenda = [
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
];

my@a=(1,2,3);@a=&$_(@a)for@$agenda;print"@a";

A few more variations on the theme

tachyon

use strict;

# a few subrefs to go, performing as specified
my $agenda = [
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
            sub{my@in=@_;for(@in){$_=$_*2}@in;},
];

# here is a little sub of 39 chars

print chain(1,2,3,$agenda);

sub chain{
    my$a=pop;
    @_=&$_(@_)for@$a;
    @_
}

# here it is as an anonymous sub
print&{sub{my$a=pop;@_=&$_(@_)for@$a;@_}}(1,2,3,$agenda);

78 letters. My solution:

Imagining? Does all here become golf?

37 letters. Though with English, one might argue that I've altered the meaning.

35 characters. :-)

Imagining? Turns all here to golf?

And restucturing produces the 29 character logical equivalent of:

All here to golf or me only.

I don't think that can be improved much. :-)
