--- Comment #13 from Patrick Uiterwijk puiterwijk@redhat.com --- Okay, though I would really like to see this being fixed.
Please note that I was mistaken: it isn't a dep for all of the packages I said, yum was tricking me with the remove-leaves plugin.
The list of packages that depend on perl-Language-Expr according to repoquery is: perl-Math-NumSeq-0:55-2.fc19.noarch perl-Math-NumSeq-0:66-1.fc19.noarch perl-Math-PlanePath-0:98-2.fc19.noarch perl-Math-PlanePath-0:110-1.fc19.noarch slic3r-0:0.9.9-5.fc19.noarch slic3r-0:0.9.10b-4.fc19.noarch
