Multiple calls on an iso

gistfile1.txt

This convoluted construction works:

class Foo
  var n: USize = 0
  new iso create() => None
  fun iso set_n( m: USize ): Foo iso^ =>
    n = m
    consume this

actor Main
  new create( env: Env ) =>
    let foo = Foo.create()
    let foo2 = (consume foo).set_n(3)
    let foo3 = (consume foo2).set_n(4)
    let destination = Other.create()
    destination(consume foo3)

actor Other
  new create() => None
  be apply( x: Foo iso ) => None
