I have a function when I want to be sure one parameter is a vector, even if it is given as number.

I thought to use `reshape(myInt,1)` but notice reshape of numbers is not in `Base`.  
No problem, I can add a method to handle it:

```julia
import Base.reshape
function reshape(x::Number, dims...) where {T <: Number}
   x = [x]
   reshape(x,dims)
end

```

But, as it is not in `Base`, I wonder if it is a good approach or it is intentionally left it out from `Base`.

I would just do something like

```julia
ensure_vector(v::AbstractVector) = v
ensure_vector(x::Number) = [x] # consider SVector(x), depending on context

```
