Description

Consider the following:

@groovy.transform.CompileStatic
void test() {
    def c = { p, q = p.toString() -> '' + p + q }
    assert c('foo', 'bar') == 'foobar'
    assert c('foo') == 'foofoo'
}
test()

Default argument creates delegate method that does not have static compilation. Running script throws java.lang.IncompatibleClassChangeError.
