in thread Perl oddities

Fatal will be a built-in pragma in Perl 6, and any code which uses the fail keyword will fail in the way specified by the caller, which might be to throw a fatal exception, or to return an unthrown exception that is behaves like undef, or to cause some form of backtracking, in the case of the pattern matching engine.

I'll talk about system elsewhere.
