I understand typealias will be removed in 1.0. I think there was a discussion of replacing it with constants.  
Has someone an idea of what it will look like?

Thanks,

Petr

The syntax looks like this: `const Vector{T} = Array{T,1}`.

Here’s an example of it in use in the standard library:

It is currently deprecated and the depwarn will tell you how to fix it.
