@spec normalize(Hologram.Compiler.AST.t()) :: Hologram.Compiler.AST.t()

Normalizes Elixir AST by ensuring that:

• single expression blocks are wrapped in block tuple
• alias atoms are wrapped in aliases tuple
• unquote fragments are expanded

Examples

iex> ast = Code.string_to_quoted!("cond do true -> 123 end")
{:cond, [line: 1], [[do: [{:->, [line: 1], [[true], 987]}]]]}
iex> normalize(ast)
{:cond, [line: 1], [[do: [{:->, [line: 1], [[true], {:__block__, [], [987]}]}]]]}
