In Should We Include a Better Alternative to File-Find in the perl5 Core?, Shlomi suggests that just as CPANPLUS and Module::Build entered 5.10 as alternatives to CPAN and MakeMaker, it's worth considering adding an alternative to File::Find to the core.
I understand the desire, but that kind of thinking digs the hole deeper.
The Perl 6 core will contain only those libraries absolutely necessary to download, configure, build, test, and install other libraries. (That trick seems to work for free operating systems.)
In a better world, Perl 5 would do the same and shed a few megabytes, as well as all of the crazy baggage required to make dual-lived modules work. Creating
Bundle::BloatMeHarder is trivial.
The one corner case I can't quite figure out is how such a scheme would increase the likelihood of dropping support for ancient versions of Perl, such as everything older than Perl 5.8.8.
