Re: [julia-users] Indexing Array with empty vector in v.0.4.
Why restrict it to Int elements? I would think that any element whose type
: Integer would be fine.

[julia-users] Indexing Array with empty vector in v.0.4.
Then again there are those of us who prefer to not think about types too much on first implementations and worry about performance afterwards. Christoph Premature optimisation is the root of all evil.
Re: [julia-users] Indexing Array with empty vector in v.0.4.
I agree. The solution is to provide good tools to identify what code is slow and why, not to try to disallow all slow code.

That seems reasonable to me.

Re: [julia-users] Indexing Array with empty vector in v.0.4.
If it's not performant (i.e. slow), I'd prefer Julia not to admit it. Even non-expert programmers like me often want the code to run fast. I prefer to get an error and fix it than slow code not knowing why.

It's Any array on 0.4, which makes me hesitate whether we should support that.

The difference is that on 0.4, `[]` is a `Array{Any}`. Write `Int[]`
should work.

Thank you.
