So write another B:: loader -- see below

A START block, then. So
#!/usr/bin/perl
eval q{
BEGIN { print 1; }
START { print 2; }
CHECK { print 3; }
INIT { print 4; }
print 5;
END { print 6; }
};
print 7;
__END__
would print "12576".
You could then write an alternative to O.pm that loads B::* from
a START block instead of from a CHECK block. The whole CHECK magic
is entirely done in O -- there's no reason to stop poeple from using
B:: modules apart from the O framework.
