As mentioned in another mail, I've removed that `variable or'.

Your example doesn't work.  Similar to suffixes like `.e' or `.ne',
`.x' is also a predefined suffix which gives the x component of a
location.  The right mechanism to get the variable's value is using
`:=':

  x = 0
  [
    box
    x := 5
  ]
  print x
