Update julia.go

[matbesancon]

They key word is abstract type, abstract or type alone can be defined as new bindings

Tested with:

package main

import (
	"github.com/alecthomas/chroma/quick"
	"os"
)

func main() {
	s := `
	struct Value
		v::Int
	end
	const r = 33
	A = zeros(3,3)
	B = rand(4,3)
	type = typeof(B)
	C = A * B'
	res = C' .+ r
	abstract v = 33
	abstract type K end
	`
	_ = quick.Highlight(os.Stdout, s, "julia", "html", "monokai")
}

Results in correct highlighting

Maybe dump that source in lexers/testdata/julia.actual then regenerate the expected output with RECORD=true go test ./lexers?

Sorry for the delay, just done it and fixed the similar issue for "primitive type"

Brilliant, thanks!
