Re: request for comments on code for ExtUtils::MY overrides

makemaker:

I've uploaded the tarballs here:
    http://holgerdanske.com/node/485


This is what I'm thinking for the next iteration of 
Dpchrist::ExtUtils::MakeMaker:

=head1 SYNOPSIS

    # Makefile.PL
    package Dpchrist::ExtUtils::MakeMaker;      # to find symbols
    use strict;
    use warnings;
    eval {
        require Dpchrist::ExtUtils::MakeMaker;
        import Dpchrist::ExtUtils::MakeMaker (
            postamble => sub {
                my $prev_text = shift;  # previous override, if any
                return join("\n",
                    $prev_text,
                    mcpani($ENV{CPAN_AUTHORID}),
                    pod2html('lib/Dpchrist/ExtUtils/MakeMaker.pm'),
                    readme('lib/Dpchrist/ExtUtils/MakeMaker.pm'),
                    release($ENV{RELEASE_ROOT}),
                );
            },
        );
    };
    warn $@ if $@;


=head3 import

    # Makefile.PL
    package Dpchrist::ExtUtils::MakeMaker;      # to find symbols
    use strict;
    use warnings;
    eval {
        require Dpchrist::ExtUtils::MakeMaker;
        import Dpchrist::ExtUtils::MakeMaker (
            SECTION => CODEREF,
            SECTION => CODEREF,
            SECTION => CODEREF,
        );
    };
    warn $@ if $@;

Daisy-chains subroutine CODEREF
into the Makefile override for given SECTION.
Any previous override function (e.g. &MY::SECTION)
will be called before CODEREF
and it's output passed as the first argument to CODEREF.
CODEREF should return a scalar string containing
the net text to be placed in the appropriate Makefile section.


Any comments?
