Here's an idea.  If a file contains "use 5.36" or higher, and it contains either 
"no warnings" or "no strict" above that use line, then a warning will be emitted 
that the "no" should be below the "use" rather than above it.  This only happens 
for programs with "use 5.36" so older programs won't get extra warnings.  The 
warnings only appear when someone makes the explicit change to add the "5.36" 
and then it will say okay you just made that change now make this change.  Also 
the use warnings behavior will be dependent on order rather than not like use 
strict. -- Darren Duncan
