no method matching @series(::Symbol)

[arturgower]

I just want to register this odd error and solution:

type A end

@recipe function f(x::A)
    rand(10)
end

@recipe function f(xs::Vector{A})
    for x in xs
      @series x
    end
end

Results in

MethodError: no method matching @series(::Symbol)

For the record, there are several workarounds, one of them being:

@recipe function f(xs::Vector{A})
    for x in xs
      @series identity(x)
    end
end
