-----------------------------------
Summary: Support expression scope variable
Key: GROOVY-11525
URL: https://issues.apache.org/jira/browse/GROOVY-11525
Project: Groovy
Issue Type: New Feature
Reporter: Daniel Sun
Let's take a look at the following code first:
{code}
int hash(Object key) {
int h;
return (key == null) ? 0 : (h = key.hashCode()) ^ (h >>> 16);
}
{code}
variable {{h}} is actually an expression scope variable, but current syntax
doesn't support.
I propose an expression scope variable syntax, e.g.
{code}
int hash(Object key) {
// h is only visible in the expression
return (int h; (key == null) ? 0 : (h = key.hashCode()) ^ (h >>> 16))
}
{code}
