Hi all,
Creating empty arrays are very common in many projects(including
Apache Groovy), e.g. stringList.toArray(new String[0]). However empty array
is immutable and can be shared safely, so I recommend to add `emptyArray`
DGSM to array class, e.g. `String[].emptyArray()` returns `new String[0]`,
and no matter how many `String[].emptyArray()` is executed, it returns the
same empty string array.
Any thoughts?
Cheers,
Daniel.Sun
