That is indeed a tricky case. But there's no way to solve it without
Mason knowing a lot more about Perl parsing than it currently does (or
cares to).
In fact, Mason 2 will fail in this case as well, because while it will
discard whitespace around certain blocks (<%perl>, etc.), it will
never discard an arbitrary whitespace line in the middle of text.
The general rule of thumb is that if you ever get a syntax error you
don't understand, or a component is behaving in a way you don't
expect, take a look at the object file (in your Mason directory) to
see how Mason is converting the component into Perl. In this case you
would see the intervening statement where Mason is appending
whitespace to your buffer.
