BEGIN blocks are a crucial part of the use mechanism and responsible for much of the flexibility many CPAN moduls can offer.

IMHO other so called "clear" languages/products just offer a multitude of specialized mechanisms which aren't really better controllable when using foreign libraries.

I doubt that those mechanisms are better suited, because normally they diminish flexibility without really enforcing security.

What's needed is a mechanism to define and enforce the personal level of trust, thats why I want to be able to hook a call-back into the executions at compile-time.

Perl's Debugger already has many possibilities to hook call-backs into various aspects and phases of execution, it would only complete this set of possibilities for debugging and introspection.

UPDATE: > This idea of “intercepts” would, IMHO, unfortunately just serve to make the code even more inscrutable than it already may be.

Which code are you talking about? I was talking about a command line switch, not of an extension of the Perl syntax. There is no  use intercept intended!
