Does it support the Syntax:

  expression = condition ? : val2

which should be the same as

  tmp = condition
  if (condition != 0)
     expression = condition;
  else
     expression = val2;

This is handy for non‐simple expression as condition.

  return sql_query("select * from table") ? : sql_query("select * from
     table2");

This is very useful! Thanks.
