Actually, i checked in perlsyn. It uses a couple of them in examples at the
very end, but doesn't really talk about them.
I frequently use the __END__ tag while i'm debugging so that i can easily
"comment out" a chunk of code at the end. I'm also using the __DATA__ tag,
and i was worried that the __END__ tag might stop perl from reading the file
at all, in which case i wouldn't get to the __DATA__. I tried it, though,
and it seems to work.
I don't suppose there's a __BEGIN__ tag, which would allow one to do this:
#!/usr/bin/perl
__DATA__
blah
blah
blah
__BEGIN__
print while <DATA>;
... ?

These are documented in perlsyn:
__END__
end of program
__DATA__
end of program, but allow this to be accessed via *PKG::DATA
__FILE__
the name of the current file
__LINE__
the number of the current line
There are also __WARN__ and __DIE__, but they're just special keys in the
%SIG hash.
