I like that kind of syntax. I'd like to propose an alternative
keyword:

  while cond1:
    dofoo()
  andwhile cond2:
    dobar()

with an analogous structure:

  if cond1:
    dofoo()
  andif cond2:
    dobar()
  else:
    doqux()

where foo is done if cond1, bar is done if (cond1 and cond2) and qux
is done if not (cond1 and cond2). For consistency with elif it could
be called anif instead?
