4 | # Pre-5.10 perls pollute %INC on unsuccesfull module |
5 | # require, making it appear as if the module is already |
6 | # loaded on subsequent require()s |
7 | # Can't seem to find the exact RT/perldelta entry |
8 | # |
9 | # The reason we can't just use a sane, clean loader, is because |
10 | # if a Module require()s another module the %INC will still |
11 | # get filled with crap and we are back to square one. A global |
12 | # fix is really the only way for this test, as we try to load |
13 | # each available module separately, and have no control (nor |
14 | # knowledge) over their common dependencies. |

16 | # we want to do this here, in the very beginning, before even |
17 | # warnings/strict are loaded |
