/*  Idea:
    * Use 8 spaces for indenting the body of clauses
    * Use 4 spaces for all other indentation
    * Set your editor to expand tab to 4 spaces

    This is highly readible while minimising effort while writing.
    Indentation that requires manual character-level alignment would be
    extremely painful (for me).
