"Reliable" mean I can rely on this software: every documented feature work as expected in all cases.

What you're doing here is adding your own personal requirements and claiming that they are basic necessities. It's just not true. Not everyone needs IPC that supports pipes and lists. Not everyone needs timers that handle someone changing the clock under them. Not everyone needs mailbox parsers that handle all possible formats and survive power failures. So why should they spend their time implementing the features you want, when they already have the ones they need? Adding those features is time-consuming and expensive.

Can you give me full list of perl features which... too complex, or too exotic and which may not be supported by eval()

You picked a great one here. Your complaint about eval is that it doesn't handle source filters? My complaint about perl is that it does handle source filters. I think you're probably the only one on the planet who wants this feature in eval. And the lack of it shows some kind of moral corruption in all perl developers?
