I have to admit never really dug into Julia.
When it was new I read about it as I was looking for a replacement of python/numpy.
But then I was really repulsed by the fact that array indices don't start at 0.
I was about to say something similar, but the last time I did, people got upset ;-)
That and people complaining about certain characters being allowed in variable names in some languages (e.g. hyphen, question mark, etc).
On it's own, 1-based indexing certainly isn't enough to keep me from using a language though.
