Difference to arrays with respect to indexing with `[]`

[mschauer]

I just noticed the discrepancy

julia> (@SVector [1])[]
ERROR: ArgumentError: invalid index: () of type Tuple{}

julia> ([1])[]
1

[mschauer]

This allowed in Base by https://docs.julialang.org/en/v1.3-dev/manual/arrays/#Omitted-and-extra-indices-1
"Indices may be omitted if the trailing dimensions that are not indexed into are all length one." (via @mbauman )

Related and partial(?) fix: #580 .

Fixed in #581

[mschauer]

Yes, fixed:

julia> m = @MArray (rand(1,1,1))
1×1×1 MArray{Tuple{1,1,1},Float64,3,1}:
[:, :, 1] =
 0.10877107273924591

julia> m[]
0.10877107273924591
