Idea: prepend singleton dimensions to array with [;;;A]

[BioTurboNick]

In the new array syntax in 1.7, we have this:

A = [1 2; 3 4]
[A;;;] # turn A into an array with at least 3-dimensions with appended singleton dimensions
#=
2×2×1 Array{Int64, 3}:
[:, :, 1] =
 1  2
 3  4
=#

And in 1.8 we'll also have #41618:

[;;;] # make empty 3-dimensional array

Based on a Slack chat, perhaps we could also have:

[;;;A] # turn A into an array with at least 3-dimensions with prepended singleton dimensions

@BioTurboNick

A = [1 2; 3 4]
[;;;A] 
#=
1×2×2 Array{Int64, 3}:
[1, :, :] =
 1  2
 3  4
=#

do you want to achieve this ?
I'm new here, I want to try my hand on this ?

@Ramanathi - if you'd like to try, you could. It would require diving into the femtolisp-based parser. It'll be a challenge though, and no guarantee the Powers That Be would think this is a good idea.

Though the output would look like:

#=
1×2×2 Array{Int64, 3}:
[:, :, 1] =
 1  3

[:, :, 2] =
 2  4
=#
