Is there a way to make haskell-updater unneccesary?

[crocket]

haskell-updater seems like a workaround. Ideally, emerge shouldn't need haskell-updater to upgrade a system that has haskell packages.

[trofi]

haskell-updater solves the problem that gentoo's package manager does not provide (yet):

• https://bugs.gentoo.org/449094
• emerge breaks haskell packages due to missing passthru subslot style depends gentoo-haskell#199

Tl;DR is: haskell ABI is too fine-grained to express in terms of Gentoo's dependency specification in ebuilds.

Does EAPI=6 solve this issue?

[trofi]

No. There is no syntax or semantics agreed to provide required functionality.
