Description

This code:

@CompileStatic
    static main(args)
    {
        def list = [1, 2, 3]

        def sum = 0
        list.each { int i -> sum += i }
        println(sum)

        sum = list.inject(0, { int x, int y -> x + y })
        println(sum)
    }

creates this error message:

Also happens without @CompileStatic:

def list = [1, 2, 3]

def sum = 0
list.each

{ sum += it }

println(sum)

sum = list.inject(0,

{ x, y -> x + y }

)
println(sum)
