43 Future suggestion: if you're going to try and be a smart ass, do it
44 when you're right. Not even sure how you could comment on transition
45 periods since the last time this occured was in '06, but hey, have at
46 it.
47
48
49 Continuing the point (w/ specific details so mgorny actually listens
50 this time), referring to
51 http://wiki.gentoo.org/wiki/Alternate_EAPI_mechanisms ,
52 the rules were to be "deploy the EAPI parsing, don't break existing
53 mechanism for <reasonable transition period>, then go nuts".
54
55
56 So... if we abide by what was actually voted upon, our options are as
57 follows:
58
59 1) No global scope crap in EAPI5. Land it in EAPI6 since that's
60 likely going to land past the compatibility window. This is what I
61 stated above; it sucks, but welcome to compatibility.
62
63 2) Stable a portage w/ the parsing now, delay EAPI5 till the
64 compatibility window is over. This sucks worse than #1 in my view.
65
66 3) Decide we don't actually care about compatibility (despite the
67 proposal being about *compatibility*), and just deploy global crap in
68 EAPI5 and ignore compatibility related breakage. Smugly label anyone
69 bringing these issues up as bikeshedding, eventually comparing them to
70 ciaran.
71
72 So... bikeshed about the options, but we choose one of them.
