But do you think the compiler works normally? Is it normal that a compiler considers two equal strings as identical? I would agree with symbols because symbols are immutable. I think this is a first bug, a bug in the compiler.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>In my opinion, there is another bug. When the collection of a stream becomes full, its is replaced by another bigger collection. So, first, the stream uses the collection you passed to the constructor, then, at a given time, this collection is replaced by a new one. I don't think it's a normal behavior. In my opinion, the collection must always be the one you gave at the beginning OR it must always be a copy. I prefer the second solution.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>So, what should be done ? I can write tests for the compiler and tests for streams to show the behavior.
