[Chicken-users] on the usage of the unsafe operations ##sys##slot and similar

[Marco Maggi]

Ciao,

  sorry  for  peeking  under  the  skirt; I'm  trying  to  get  a  basic
understanding of the  core usage and memory layout of  Scheme values; is
it correct that:

* We can  use ##sys#setislot to  store any  immediate value in  a Scheme
  vector?

* We   can  use   the  system   operations  ##sys#slot,   ##sys#setslot,
  ##sys#setislot , ##sys#size on every Scheme object whose memory layout
  is similar to the one of Scheme vectors?

TIA
