To call the old method, you want invoke, or now @invoke:

julia> @which show(stdout, 3.14)
show(io::IO, x::T) where T<:Union{Float16, Float32, Float64} in Base.Ryu at ryu/Ryu.jl:111

julia> Base.show(io::IO, x::Float64) = 
             Base.@invoke show(IOContext(io, :compact=>true)::IO, x::Union{Float16, Float32, Float64})

julia> pi .^ (0,1,2)
(1.0, 3.14159, 9.8696)
