2 | ### This version is rather 5.8-centric, because DBIC itself is 5.8 |
3 | ### It certainly can be rewritten to degrade well on 5.6 |

21 | # loaded on subsequent require()s |
22 | # Can't seem to find the exact RT/perldelta entry |

24 | # The reason we can't just use a sane, clean loader, is because |
25 | # if a Module require()s another module the %INC will still |
26 | # get filled with crap and we are back to square one. A global |
