Why? Very little on the web is critical. If it mostly renders, it's mostly good enough. shrug It's not like the big vendors with fancy programmers and difficult types release without bugs and security issues. But so what? Life goes on.
Which is what "On Error Resume Next" was doing by overwriting the current error handler. Seems to me that it was simply overused. Implicitly ignoring errors is more a C thing.
It's even worse than PHP and JS were built around it.
Errors should never pass silently unless explicitly silenced.
