WADLER'S LAW OF LANGUAGE DESIGN

In any language design, the total time spent discussing
a feature in this list is proportional to two raised to
the power of its position.

    0. Semantics
    1. Syntax
    2. Lexical syntax
    3. Lexical syntax of comments

(That is, twice as much time is spent discussing syntax
than semantics, twice as much time is spent discussing
lexical syntax than syntax, and twice as much time is
spent discussing syntax of comments than lexical syntax.)
