hcat and vcat don't behave like arrays
julia> hcat(Vec(3,4),Vec(5,6))
1×2 Array{FixedSizeArrays.Vec{2,Int64},2}:
Vec(3,4) Vec(5,6)
julia> vcat(Vec(3,4),Vec(5,6))
2-element Array{FixedSizeArrays.Vec{2,Int64},1}:
Vec(3,4)
Vec(5,6)
I was expecting that Vec would behave like an Array here, i.e. that hcat would produce a Mat{2,2} and vcat would produce a Vec{4}.
@stevengj Not sure if you saw #159? I realize there are good reasons for using FIxedSizeArrays (including backward compatibility, integration into other packages, etc), and don't want to steal thunder from @SimonDanisch for this awesome package, but I wanted to mention that the issues you raised today are not present in StaticArrays.jl.
@andyferris, thanks for the tip. I have to admit that the variety of packages for fixed-size arrays (FixedSizeArrays, ImmutableArrays, StaticArrays) confuses me, and I was unclear on which one I should use. I'll take a look at StaticArrays.
No worries. There was a suggestion to add note to the READMEs of these packages which might help with this.
Sorry about this, that's my fault. I just don't feel comfortable about spreading the deprecation of FixedSizeArrays before I haven't actually moved away my own packages! Lets get this done this week and have an announcement on the user list etc!

Sounds good. :smiley: I'm currently making a few architectural changes to StaticArrays and will tag a new minor release when that is in reasonable shape (a couple of days) so we can time it with that.
On a related note, how are you finding using StaticArrays for geometry? Did you get a Point type working the way you like?
I don't actually care much about the distinction between Point and Vec in my application (I don't need to dispatch on the difference, anyway), so I'm not planning defining a Point type. If I have any problems with StaticArrays, you'll notice me filing a slew of issues. 😄
