How about this: plain "use autodie" fatalizes *all* functions and gives 
a warning when the user uses the exotic (or should I say esoteric) 
system() call style. To turn off the warning the user has two 
possibilities: explicitely state "use autodie qw(system)" or turn off 
autodie for the exotic system() call by prefixing it with "no autodie 

Come to think of, when would that warning be emitted? When the first 
plain "use autodie" is encountered? Does the local "no autodie 
qw(system)" stand a chance to suppress that warning?

Sounds like an interesting challenge... ("interesting" as in "may you 
live in interesting times").
