Hello!

I'm happy to announce the first release of HoleyMonoid, a datatype that 
helps you build monoids with holes in them. The holes are filled in 
later using normal function application. For example:

>  > let holey = now "x = "
>              . later show
>              . now ", y = "
>              . later show
>  > run holey 3 5
>  "x = 3, y = 5"

The library is available on Hackage:
    http://hackage.haskell.org/package/HoleyMonoid

Thanks to David Menendez for the name and Sjoerd Visscher for help with 
rewriting and simplifying. :-)

Martijn.
