there was a really witty comment in ‘stdlib/LinearAlgebra/src/deprecated.jl’ (gone now too):

- ## goodbeye, eye!
- export eye
- function eye(m::Integer)
-     depwarn(string( ...
- ...

I think we have the first function name for MatlabPuns.jl:

export goodbeye
function goodbeye(m::Integer)
    return Matrix{Float64}(I, m, m)
end
function goodbeye(::Type{T}, m::Integer) where T
    return Matrix{T}(I, m, m)
end
function goodbeye(m::Integer, n::Integer)
    return Matrix{Float64}(I, m, n)
end
function goodbeye(::Type{T}, m::Integer, n::Integer) where T
    return Matrix{T}(I, m, n)
end
function goodbeye(A::AbstractMatrix{T}) where T
    return Matrix(one(T)I, size(A))
end
function goodbeye(::Type{Diagonal{T}}, n::Int) where T
    return Diagonal{T}(I, n)
end

Hmm, what others would work?

• linspace → linspacedout
• diagm → diagmeh
• flipdim → flippingoutdim
• eig → whyohwhyg
• sum(A, n) → dimsum(A, n)

… actually that last one kind of makes sense…
