Paul King updated GROOVY-10953:
-------------------------------
Description:
The following code runs fine without {{TypeChecked}} but fails in static
checking mode.
{code}
@groovy.transform.TypeChecked
def method() {
def (x, y, z) = 1..3
assert "$x $y $z" == '1 2 3'
}
method()
{code}
The error is:
{noformat}
[Static type checking] - Multiple assignments without list or tuple on the
right-hand side are unsupported in static type checking mode
{noformat}
{code}
The workaround is to replace the multi-assignment with:
{code}
def (x, y, z) = [1, 2, 3]
{code}
But since we know the range expression, we can do further checking.
