Can't plot Vector of Quantity with open ended child type

[luke-pikaart]

This errors out when trying to ustrip() and uconvert():

using Plots, Unitful

x = 0:10

function foo(x) 
    if(x > 5) 
        return 1u"A"
    else 
        return 1.0u"A"
    end
end

y = foo.(x)

plot(y)

y is type Vector{Quantity{T, 𝐈, FreeUnits{(A,), 𝐈, nothing}} where T}

Is this the intended behavior? It seems like for the purposes of plotting we should try to be as flexible as possible and accept as many inputs as possible.
