 The parser seems to be broken. Attempting to build
 [http://hackage.haskell.org/package/basement basement] yields:

 {{{
 Basement/Nat.hs:15:46: error: parse error on input ‘*’ | 15 | , type (<=),
 type (<=?), type (+), type (*), type (^), type (-) | ^
 }}}

 This is actually in 8.6.0, but there is no version option for this.
