Making another type of list, for the immediate purpose of generalizing the null-element-filling of setSize().

? def listList := [].diverge(List)
# value: [].diverge()

? listList.setSize(1)

? listList
# value: [[]].diverge()

test failure case of setSize (no trivial value)
  
  ? def plainList := [].diverge(TextWriter)
  # value: [].diverge()
  
  ? plainList.setSize(1)
  # problem: no such method: org.erights.e.elib.print.TextWriterGuard#getTheTrivialValue/0
  
  ? plainList
  # value: [].diverge()

pop

  ? listList[1] := [44]
  # value: [44]
  
  ? listList.pop()
  # value: [44]
  
  ? listList
  # value: [[]].diverge()
  
  XXX zero length failure case

ensureSize

  ? listList.ensureSize(3)
  
  ? listList
  # value: [[], [], []].diverge()
  
  ? listList.ensureSize(2)
  
  ? listList
  # value: [[], [], []].diverge()
  
  
  ? listList.ensureSize(3)
  
  ? listList
  # value: [[], [], []].diverge()
  
  ? listList.ensureSize(def _ {to __conformTo(_) :any {return 4}})
  
  ? listList
  # value: [[], [], [], []].diverge()

 negative size is OK, because ensureSize never decreases the size.

  ? listList.ensureSize(-3)
  
  ? listList
  # value: [[], [], [], []].diverge()
  
replace/5

note: I wrote append/1 first, then turned it into a broken replace/5 implementation, so these tests don't check the appendish functionality. This should be fixed. '
