Cheers for your comments, very enlightening!  I'm afraid I'm out of my
depth making this decision here.  I'm happy to let my computer rebuild
those 200 packages to see whether the dependent packages build — but
I'm not sure how I would go about testing that.  See below for a theory…?

Interesting… so to establish the packages to be rebuilt as a result of
my patch series, would that be:

guix refresh -l perl-scalar-list-utils perl-parse-cpan-meta      \
perl-cpan-meta-requirements perl-yaml perl-variable-magic        \
perl-time-duration-parse perl-test-warnings perl-test-simple     \
perl-test-exception perl-test-cleannamespaces perl-sub-name      \
perl-params-validate perl-package-deprecationmanager perl-moose  \
perl-module-runtime-conflicts perl-devel-partialdump             \
perl-devel-overloadinfo perl-cpan-meta-check perl-common-sense   \
perl-clone perl-class-load perl-capture-tiny perl-b-hooks-endofscope

Building the following 24 packages would ensure 248 dependent packages
are rebuilt: edirect-4.10 perl-modern-perl-1.20150127
perl-text-neattemplate-0.1101 perl-encode-detect-1.01
perl-list-someutils-0.52 perl-db-file-1.838 pam-krb5-4.7
perl-test-trailingspace-0.0300 sslh-1.18 perl-mail-spf-v2.9.0
gerbv-2.6.1 netsurf-3.6 perl-config-ini-0.025 perl-anyevent-i3-0.16
tophat-2.1.0 perl-test-class-most-0.08 gnucash-2.6.15 surfraw-2.2.9
biber-2.5 biber-next-2.6 stow-2.2.2 perl-x11-xcb-0.16 roary-3.7.0
hydra-20151030.1ff48da

Does this mean, that in order to test this I would now simply try to
rebuild the 24 listed packages?

Cheers,

Alex
