If `A = [1,2; 3 4]` What is the difference between `b = view(A, :, 1)` and `b = @view A[:,1]`

Is the macro form just shorthand for the other?

Thanks

Yes, just for convenience. Also, the macro supports using `end`.

(There is also `@views`)

The way to check this is to use `@macroexpand`, which shows you what the macro expands to:

```julia
julia> using MacroTools # makes the output a bit cleaner

julia> @macroexpand( @view A[:, 1] )
:(true && (view)(A, :, 1))

```
