Please let us know when this branch is available --- once you have
something semi-functional for the ess-mode a julia-mode can inherit
from, I would be happy to start incorporating changes.

In the meantime, I will keep piling up code in
https://github.com/tpapp/ESS-julia-extensions , building on (and
occasionally hijacking) existing ESS stuff. I am still discovering
corner cases that I need to deal with (eg I just fixed $ interpolations
in strings), so I can spend the time in a useful way until changes above
happen.

BTW, with the extensions above, I find ESS/julia is quite usable,
definitely better (for my purposes) than anything else I have seen,
including Juno, the dedicated Julia editor.

Best,

Tamas
