Description

I have test the following script, named as argumentsTest.groovy, on several groovy releases and CVS Head.
------------------------------------------
def fn(a, b, c, d) {
return a + b + c + d
}

println fn(1, 2, 3, 4)
println fn([1, 2, 3, 4]) // Expected fail
println fn([1, 2, 3]) // Expected fail

Executed on Groovy-1.0-JSR-03-SNAPSHOT (CVS HEAD)
