in thread use Fatal;

Another problem with the current version is that it only overrides the given functions in the current package, so all modules and embedded packages must also use it to get the functionality you might want. 

#!/usr/bin/perl -w
use strict;
use Fatal qw/open close/;

package Foo;
#use Fatal qw/open close/;
sub bar {
    open(FILE,'dfdsadf');
    close FILE;
}

package main;
Foo::bar();

It should at least be a lexically scoped pragma so the above would be fatal without reissuing the use statement. I'm not sure how it could be made to globally overide such functions in all used packages.

    That is what *CORE::GLOBAL::open= coderef is for. And if it only makes things fatal when in a void context, then this shouldn't be much of a problem for module code that doesn't know whether the user might use this or not.

    You can write code that would break in such cases but I don't consider such code to be reasonable so I don't mind. (: 

        open( FILE, "< this.txt" );
    warn "Can't read this.txt: $!\n"
      unless  defined fileno FILE;
