Without having any specific knowledge of the internals, I would guess
that patching basically amounts to adding support for Unicode 10.

That is a good suggestion.

Julia module packages need not depend on julia if we use versioned
module paths as suggested by upstream (but currently reverted by
debian/patches/unversioned-system-load-path.patch). We could have a
dh_julia that installs modules to the versioned path (and symlinks
between multiple versioned paths to support multiple Julia versions).
That is the packaging model used for Lua modules, which I think would
be a good fit for Julia, too. Since Julia 0.5, libjulia is installed
as a system-wide library for the purpose of embedding, thus it should
be possible to install Julia modules without the julia executable.

Unfortunately yes. I wonder if it were feasible to forward-port pkg
from Julia 0.4, but it seems certain that upstream would not be happy
to receive bug reports as a consequence of such a transplant.
