A warning to the reader -- what talexb has done using the ||= operator is valid and useful, but has a catch. It isn't truly a default-setting operator (see Perl 6's //= operator) but rather a "set me to the following value if my current value evaluates to false".

Note that any time a false value is a valid value for your variable, using the ||= to set the default will fail to produce the desired results.
