`reshape` with `Colon` fails on `VectorOfArray` about recursivearraytools.jl

[visr]

The UndefVarError is fixed in #272, but that doesn't fix this issue, which I also ran into. Now your first example gives:

x = VectorOfArray([randn(2) for _ in 1:4]);
reshape(x, :)
# -> DimensionMismatch: parent has 8 elements, which is incompatible with size (4,)

This is related to the somewhat odd situation that length(x) == 4 and size(x) == (2,4), i.e. it seems to behave like both a vector and a matrix, but x isa AbstractMatrix.

The function vec according to the Base docs should return the same underlying data, but vec(x) creates a copy.

For my 1D example I could use reshape(x, prod(size(x))) as a workaround.

For me this is a deal-breaker. I want one or the other. It's easy for me to create a vector of vectors, but I explicitly want to use this type to treat those as an AbstractMatrix.

yeah and that would be changed if someone has a good way to do it.

This works now. I think the issue can be closed?

Indeed, reshape(::VectorOfArray, ::Any...) was redefined in #290, and this now works.
