Yes, true, I just copied it so that I knew what character it was.
The output format isn't intended to be valid input format in either version
of Julia, e.g. on 0.4:
julia> 2x3
ERROR: UndefVarError: x3 not defined
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
(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
