To cope with the new versioning system's use of at least three significant
digits for each version component, the method used for incrementing the
that with a C<use attrs> pragma in the body of the subroutine.
That can now be accomplished with declaration syntax, like this:
- sub mymethod : locked method ;
+ sub mymethod : locked method;
...
sub mymethod : locked method {
...
}
- sub othermethod :locked :method ;
+ sub othermethod :locked :method;
...
sub othermethod :locked :method {
...

automatically undef-ed.

necessary APIs and datatypes, you should be able just to go ahead and
use them, for threads by Configure -Dusethreads, and for 64 bits
either explicitly by Configure -Duse64bitint or implicitly if your
