Detailed Description

BlockDataRegion - A region that represents a block instance.

Blocks are represented with two kinds of regions. BlockCodeRegions represent the "code", while BlockDataRegions represent instances of blocks, which correspond to "code+data". The distinction is important, because like a closure a block captures the values of externally referenced variables.
