Every word (the thing what author calls a "variable") has a binding. In short, it's a pointer to the namespace where value associated with that word resides.
Blocks can nest any other value, including words. At any point in runtime you can change this pointers (bound word to some value) for every word in a block or for separate words.

You can pattern match streams of values, and those values can be any lexical form that Red supports.

Sounds somewhat similar to OMeta (http://www.tinlizzie.org/ometa/) which can pattern match streams of objects.
With contexts it sounds like almost every word can be late bound? Also it seems blocks and contexts are decoupled which means you could evaluate multiple blocks from different parts of your program in the same context, or give each a unique context, etc?
