+In fact, the above is a specific instance of a more general problem:
+we can't guarantee to produce BEGIN blocks or C<use> declarations in
+exactly the right place. So if you use a module which affects compilation
+(such as by over-riding keywords, overloading constants or whatever)
+then the output code might not work as intended.

+This is the most serious outstanding problem, and will be very hard

If a keyword is over-ridden, and your program explicitly calls
the built-in version by using CORE::keyword, the output of B::Deparse
-will not reflect this.
+will not reflect this. If you run the resulting code, it will call

+should be an option to B<always> print keyword calls as C<CORE::name>.)
