  h1. Data Structures
    integer => Fixnum
    Float => in Ruby exact precision, but going to/from DB turns it into C double (not exact precision)
              Use BigDecimal to stop this behavior, or integers (cents)
    Strings - big topic!
    Symbols vs. Strings
	Regex -> like perl (Oniguruma regular expression library http://www.geocities.jp/kosako3/oniguruma/)
    yada yada 
	Array
	Hash - Associative Array, Dictionary, etc.

  h1. Control Flow
