Hmm, does that mean that regular
  assert(1);
would trigger a compiler warning that the user is throwing away the result?
it would kind of make sense/be useful if assert() would return the result, like:
  var not_zero = assert(2+2);
  // not zero == 4

An alternative might be to allow casting "void" to int like:
  var myvar = assert(1) as int;
