Warnings will catch that for you.
%foo = (bar => "xyzzy")
print "-$foo{bar}-"; # -xyzzy-
print "-$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.
