Idiom # 195: Pass a two-dimensional array

See programming-idioms.org:

Code

foo a

foo (a array2 f64) unit is
  say "array size {a.length0}×{a.length1}"

  for
    s := 0.0, s + v * (i.as_f64 + 1) * (j.as_f64 + 1)

    # NYI syntax sugar for tuples not supported, should be
    #
    # (i,j,v) in a.enumerate2
    e in a.enumerate2
    i := e.values.0
    j := e.values.1
    v := e.values.2

  else
    say "sum is $s"

What are effects?
