Warnings will catch that for you.

print "-$foo {bar}-"; # - {bar}-
Putting a space in the middle of a variable is just
a wee bit different from indenting lines within a
function.
$a = 1;
print $a - -5; # 6
print $a -- 5; # error
print q qhelloq; # hello
print qqhelloq; # qqhelloq
All of these examples are highly contrived, and not
at all the same as wanting to indent lines to
properly reflect a nested structure and being
told that no, those lines should not be indented,
because the leading whitespace is significant.
And as for having blank lines be significant...
the English language lacks the words to describe
my view of that. At this point I'm thinking I'll
probably continue to use comments as I have been
doing, after all. The prospect of being able to
automatically generate documentation from the
POD comments embedded in the code was attractive
to me in principle, but apparently it's not
flexible enough to be used at all the way I want.

Is it?
%foo = (bar => "xyzzy")
print $foo{bar}; # xyzzy
print $foo {bar}; # xyzzy (!!!)
print "-$foo{bar}-"; # -xyzzy-
print "-$foo {bar}-"; # - {bar}-

Yes, absolutely, without qualification, it is
fundamentally different. Indenting everything within
a block is a strongly-recommended best practice in
good coding style, because it greatly enhances clarity.
Being told that I shouldn't do that with POD is as far
as I'm concerned a good enough reason in itself not to
use POD (within blocks -- which is where I wanted to
put the information in question), because I would have
to adopt an unclear coding style in order to do so.
Now I understand why people who use POD stick it all
in big huge chunks, rather than interspersing it
through the code like comments -- because fundamentally
it's not designed to be interspersed the way comments
can be. (I had been led to believe otherwise.)
Putting whitespace in variable names (as,
$foo {bar}) is something I would do in
an obfuscation, to make the code *less* clear. If it
alters the meaning, so what? It isn't something I'd
normally expect good code to ever do, so at worst it's
a very minor gotcha.
