Nik Everett 434fa4bd26 Docs and tests for painless lack of boxing for ?: and ?. (#21756)
NOTE: The result of `?.` and `?:` can't be assigned to primitives. So
`int[] someArray = null; int l = someArray?.length` and
`int s = params.size ?: 100` don't work. Do
`def someArray = null; def l = someArray?.length` and
`def s = params.size ?: 100` instead.

Relates to #21748
