Version 0.21 Released

I made an executive decision and removed the @(...) notation for lists so that I can use the @ symbol as a projection operator.

Just to limit the amount of time v0.2 is left in the wild with the old notation, I've released a minor update.

This update only includes 2 changes:

1. The @(...) list notation has been replaced with {...} (curly brackets)
2. The projection operator (see the documentation for lists)
