I really like this.

Here are 2 problems I can think of. But please don't "shut up about
it" -- I like the solution, but these need to be sorted out!
1. It requires the perl parser know about indentation. Of course we
all know that tabs are 8 characters wide (I myself make a point of
bludgeoning anyone who says otherwise), but do we really want to
open this can of worms?
2. Existing practice for here docs will have the contents of the here
doc on the left margin. People might want to preserve that. For
instance, it makes sense if you're here-docking a bunch of 80 char
lines.
(2) can be solved, and the ambiguous "no matter how far left or right
the expression be be indented" resolved, by saying that indentation of
the here doc is relative to the terminator (*not* the statement that
launched it). This might also make slightly better sense when you
have 2 here docs in one line:
print << FIRST_HERE_DOC; print << SECOND_HERE_DOC;
This is on the left margin.
This is indented one char.
FIRST_HERE_DOC
This is indented one char.
This is on the left margin.
SECOND_HERE_DOC
But (1) needs to be resolved (and don't say "use tabs 8"!).
