[Haskell-cafe] GADT vs Arrows for parsers/FSMs/etc.

[S. Alexander Jacobson]

It seems like Haskell has two emerging idioms for parsing and fsms:

GADTs and Arrows.

I am thinking about using one of these idioms to represent server 
structure in a future version of HAppS but I'm not sure where to 
start.  Why would one choose one or the other?
