Quotes of the Week

   * monochrom: great way to answer a semantics question by commenting
     on the font ... "what is the semantics of IO?" "the I may be
     narrower than O in some fonts, and same width in some other fonts"
     ... "on very old typewriters, it also denotes the number 10 (ten),
     for those of you looking for a denotation"

   * elliott: |\/|/-\|-|-|=|\||} is my preferred mappend operator

   * merijn: rostayob: I used to be a functional programmer like you,
     but then I took an UML diagram to the knee >.>

   * mauke: monoids are simple
     elliott: And as we all know, monads are basically just monoids!
     monochrom: haskell is basically just ascii

   * O'Keefe: "Elegance is not optional."

   * O'Keefe: "If I don't write it, I won't wrong it."

   * kmc: "monads are like containers, as long as you forget everything
     you know about containers, and treat it as a synonym for 'monad'"

   * Enigmagic: this calls for mfix and some tequila
