perldoc perlref contains this statement:

       2.  Anywhere you'd put an identifier (or chain of
           identifiers) as part of a variable or subroutine name,
           you can replace the identifier with a BLOCK returning
           a reference of the correct type.

So, whenever you want to write:

   @somearray = @solution;

You can write:

   @{ some_expression_that_yields_a_reference_to_an_array } = @solution;

The stuff inside the curlies is an array ref.
