[julia-users] Array printing in 0.5

[daycaster]

(I'm just untangling some confusion on my end. Is the following correct?)

In 0.4, array dimensions were printed like this:

    julia> zeros(2,3)
    2x3 Array{Float64,2}:
     0.0  0.0  0.0
     0.0  0.0  0.0

In 0.5, the "x" is replaced with a "×":

    julia> zeros(2,3)
    2×3 Array{Float64,2}:
    0.0  0.0  0.0
    0.0  0.0  0.0

but apparently this character isn't a multiplication, but the cross-product 
operator:

    julia> 2×3 # copy/paste from above 
    ERROR: MethodError: no method matching cross(::Int64, ::Int64)
     in eval(::Module, ::Any) at ./boot.jl:234
     in macro expansion at ./REPL.jl:92 [inlined]
     in (::Base.REPL.##1#2{Base.REPL.REPLBackend})() at ./event.jl:46

But to get this character you type `\times`, although 'times' is (according to 
http://docs.julialang.org/en/release-0.4/manual/mathematical-operations/) the 
name for "*", but this is the symbol for the `cross()` function...

So wouldn't it be more logical to report the size of arrays using "by"?

     julia> zeros(2,3)
     2 by 3 Array{Float64,2}:
     0.0  0.0  0.0
     0.0  0.0  0.0
