I was fully aware that LLVM 3.8 has not been released yet. However, I
neglected to consider whether llvm-toolchain-snapshot is in testing.

Julia 0.4 requires LLVM == 3.3 or >= 3.8 to perform adequately.
LLVM 3.4 to 3.7 exhibit significant to grave performance issues
depending on the architecture [1], which the upstream maintainers
are aware off.

As an alternative to not having Julia 0.4 in Debian at all, would you
agree to the Julia team reuploading the LLVM 3.3 package to unstable
under our maintainership?
We would transition to LLVM 3.8 once Julia 0.5 is released next year.
On the topic of LLVM, I have suggested [2] to promote selected LLVM
versions to long-term supported (LTS) releases that are maintained
by downstream users.
