Then I'm seriously rocking your world.
In Perl 6 a lexical variable is scoped to the block in which it's declared.
Since C<$cond> is declared in the block *containing* the C<while> and C<else>,
it's scoped to that block. So you can use it inside the C<while>'s block,
inside the C<else>'s block (assuming Larry allows such a construct), and in
the following C<print> statement.
