I guess it's just another pattern that becomes available to make for more
terse code. An example might be a caching engine's 'get' method, i.e.
cachedValue = cacheEngine.get( cacheKey, functionToGetValueWhenNotInCache
);
rather than:
if ( not cacheEngine.exists( cacheKey ) {
cacheEngine.set( cacheKey, functionToGetValueWhenNotInCache( cacheKey )
);
}
cachedValue = cacheEngine.get( cacheKey );
