It delays the actual import of the module until you try to use it.

For decimal, that's not much of an advantage, but some modules are quite 
expensive to import the first time, and you might not want to pay that 
cost at application start-up.

Personally, I have no use for this, but people have been talking about 
lazy importing recently, and I wanted to see how hard it would be to do.
