Parametric method using parametric type of Complex

[xianrenb]

I believe there is an issue for parametric method using parametric type of Complex.

$ cat temp.jl
F = Float64
Complex{F}

type MyType{T}
a::T
end

function f{A}(z::Complex{A})
end

function g{B}(z::MyType{B})
end

julia> using Lint

julia> lintfile("temp.jl")
temp.jl:8 [f ] ERROR Lint fails to parse Complex{A}
TypeError(:Complex,"T",T<:Real,Any)
temp.jl:8 [f ] INFO Argument declared but not used: z
temp.jl:11 [g ] INFO Argument declared but not used: z

julia> include("temp.jl")
g (generic function with 1 method)
