That would be perlmod. It's about halfway down the page, and states,
The begincheck program makes it all clear, eventually:
#!/usr/bin/perl

# begincheck

print         " 8. Ordinary code runs at runtime.\n";

END { print   "14.   So this is the end of the tale.\n" }
INIT { print  " 5. INIT blocks run FIFO just before runtime.\n" }
CHECK { print " 4.   So this is the fourth line.\n" }

print         " 9.   It runs in order, of course.\n";

BEGIN { print " 1. BEGIN blocks run FIFO during compilation.\n" }
END { print   "13.   Read perlmod for the rest of the story.\n" }
CHECK { print " 3. CHECK blocks run LIFO at compilation?s end.\n" }
INIT { print  " 6.   Run this again, using Perl?s -c switch.\n" }

print         "10.   This is anti-obfuscated code.\n";

END { print   "12. END blocks run LIFO at quitting time.\n" }
BEGIN { print " 2.   So this line comes out second.\n" }
INIT { print  " 7.   You?ll see the difference right away.\n" }

print         "11.   It merely _looks_ like it should be confusing.\n"
