That looks really nice. And I like that it defaults to doing the right thing. I always have to read the docs when using gdb, as it happens so rarely that I forget the commands for doing things...and it definitely does not default to useful behaviors, certainly not just hitting &quot;enter&quot; to do the next obvious thing.<p>A debugger doesn&#x27;t take the place of a good REPL, but it&#x27;s a useful component of a good REPL.
