Recently I was debugging some code. That happens. But this code was cluttered with @-operators suppressing error messages. That's annoying. So I wrote a simple extension disabling this operator. That helped.
I then proposed that extension to pecl, while doing that I found out that Gopal has written a similar extension before. After short discussions we added that extension, using the name scream to pecl and released the extension there. Documentation is written and committed and should appear in the PHP documentation within hours.
