             Summary: Change precedence priority of ** compared to pre/post inc/dec and unary plus/minus
                 Key: GROOVY-7428
                 URL: https://issues.apache.org/jira/browse/GROOVY-7428
             Project: Groovy
          Issue Type: Improvement
            Reporter: Paul King


Currently the precedence order is:
{noformat}
level 1: post inc/dec
level 2: power
level 3: pre inc/dec
{noformat}
The original intention, I believe, was always:
{noformat}
level 1: post inc/dec
level 2: pre inc/dec
level 3: power
{noformat}
This leads to some unintuitive behavior:
while these are the same:
{code}
println (-9 + 2)  //  -7
println ((-9) + 2)  //  -7
{code}
these are different:
{code}
println (-9 ** 2)  //  -81  actually: println (-(9 ** 2))
println ((-9) ** 2)  //  81
{code}
Similar anomalies occur between {{**}} and {{++}}/{{--}}
