Be aware that { } blocks in Ruby don't have the same meaning as { } 
blocks in C-like languages. They're not used for grouping statements; 
rather, they're used as code blocks (cf. anonymous subroutines, closures 
etc).

Also, { } is an empty hash, which can sometimes be confusing.

  x = lambda { }  # an empty code block
  x = { }  # an empty hash
