Blocks are blocks. Stylistically, some people prefer braces, some
people prefer do/end. There are people who will do everything they can
to make sure that they always use the same style. There are people who
use {} for blocks that return a value (and the exception handler is
*very* important there) and do/end for those that don't. There are
people who use {} for one-liners and do/end for multi-liners.

The curly syntax is *not* just a shorthand. It has a different binding.
