[GitHub] [groovy] eric-milles commented on pull request #1732: GROOVY-10223: support conversion of `Optional` to array/collection

   You can also do this, but I don't think it is an improvement over "optional.map(String::length).orElse(null)" or "optional.orElse(null)?.length()":
   ```groovy
   def nothing = Optional.empty(), something = Optional.of('foo')
   def value = nothing*.length()?[0]
   assert value == null
   value = something*.length()?[0]
   assert value == 3
   ```
