Range operation with SSAS2005

Today, while digging into time intelligence wizard-generated scripting,  I discovered that Analysis Services 2005 has a new syntax for range operations that give us more flexiblity. You can define a range of members like “all members from X to the end” placing NULL in place of the undefined terminating member (we could imagine this like an infinite keyword).

Now you can write:
Date.Year.[2004] : NULL

Time intelligence use it into the Year Over Year calculated member, since this member must be calculated for all the years except the first one.
Date.Year.Members(1) : NULL

I think this sintax will be very useful even in several other circumstances, even if Date dimension is the most important one.
