• # 1.3 Do block
  
  A KC3 **do** block is a source code block. It starts with `do` or `{` and
  ends with `end` or `}` respectively.
  It can be passed to a special operator or macro function to
  be evaluated explicitly in C with `env_eval_do_block` (see
  `libkc3/env_eval.c`).
  
  A block evaluates all its instructions in turn, and returns the value
  of the last expression.
  
  ## 1.3.1 Examples
  
  ```elixir
  ikc3> do
  ikc3>   1
  ikc3>   2
  ikc3>   3
  ikc3> end
  3
  ikc3> quote do
  ikc3>   1
  ikc3>   2
  ikc3>   3
  ikc3> end
  do
    1
    2
    3
  end
  ikc3> type(quote do
  ikc3>   1
  ikc3>   2
  ikc3>   3
  ikc3> end)
  Block
  ```
