StringIndexError

[jacob-roth]

I get a weird error trying to paste a function into the REPL. My code in a text editor is:

using ForwardDiff

const Y = [  20.0  -10.0  -10.0
            -10.0   20.0  -10.0
            -10.0  -10.0   20.0]
const P = [ -1.0; -2.0; 3.0]
const Q = [ -0.1; 0.0; 0.1]

function G(rθ; Y, P, Q)
    N = length(rθ); n = div(N, 2)
    r = rθ[1:n]; θ = rθ[(n+1):(N)]
    vr = r .* cos.(θ)
    vi = r .* sin.(θ)
    return vr' * Y * vr + vi' * Y * vi + P' * θ + Q' * log.(r)
end
function dG(rθ; Y, P, Q)
    g = rθ -> G(rθ, Y=Y, P=P, Q=Q)
    return ForwardDiff.gradient(g, rθ)
end
function d2G(rθ; Y, P, Q)
    g = rθ -> G(rθ, Y=Y, P=P, Q=Q)
    return ForwardDiff.hessian(g, rθ)
end
r = [1.0; 1.0; 1.0]
θ = [0.0; 0.0; 0.0]
rθ = [r; θ]
G(rθ; Y=Y, P=P, Q=Q)
dG(rθ; Y=Y, P=P, Q=Q)
d2G(rθ; Y=Y, P=P, Q=Q)

and when I paste everything in to the REPL, everything is fine except for d2G(rθ; Y=Y, P=P, Q=Q). It disappears, and I get the following error:

However, it works fine if I actually enter the function's name letter-by-letter in the REPL. I wonder what I'm messing up?

OhMyREPL.jl is messing up the string handling somewhere. Will look at it in the upcoming days.
