Ok: If we take this notion and enshrine it in stone:
If we assume Bash 4 is a seperate language from Bash 3, as its
syntax-backwards-incompatible, is it fair to suggest that for some
future EAPI which require Bash 4, that the extension change to suit?
ie: move from .ebuild to .ebuild4 , where '.ebuild' conveys the
format is bash, and that '.ebuild4' is bash4 only?
That way you have a forwards declaration of the syntax/file format
required to parse the file, but no declaration of the EAPI, so you're
not breaking encapsulation.
This is breaking the direct file=3D=3Deapi connection, but still
maintaining a loose file<->eapi connection.
Its /sort/ of like the "one time extension change" proposal, except
its less 'arbitrary' than something like .eb , and it gives us the
future option of changing the suffix again if bash 5 comes out with
different syntax.
Then we can do
.ebuild =3D EAPI 0 - 4 & bash >=3D 3
.ebuild4 =3D EAPI5 - 9 & bash >=3D 4
.ebuild5 =3D EAPI10 - 15 & bash >=3D 5
Thoughts?
