It doesn't ~need~ an alias. It's just quite handy sometimes when you
are creating lots of nested objects to avoid having to type new all
the time. For example, in a report DSL, you could use something like:

  r = Report(
    :header => Header( :title => "My report" ),
    :body   => Body( :rows => Query(:sql => "SELECT * FROM Supplier"))
    )

instead of

  r = Report.new(
    :header => Header.new( :title => "My report" ),
    :body   => Body.new( :rows => Query.new(:sql => "SELECT * FROM Supplier"))
    )

Not a big gain, but in my opinion, the .new in the second example is
just adding noise. It's a matter of taste I guess.
