Description

the following code when entered into groovyConsole works on 4.0.13 but breaks on 4.0.14/4.0.15

import groovy.transform.*

@CompileStatic
static foo() {
    def l = [37, 34, 12, 412, 5]
    [l, [0] + l].transpose().each { int i, int j ->
        println "foo $i $j"
    }
}
foo() 

The error is

1 compilation error:Incorrect number of parameters. Expected 1 but found 2
 at line: 6, column: 35

The correct output should be

foo 37 0
foo 34 37
foo 12 34
foo 412 12
foo 5 412
