However, each of the clauses is actually an output routine to send the expression that it denotes to a remote server, and a parser for receiving the results. Since a clause is really a pair of operations, it doesn't seem possible to formulate a monad that will compose all the output routines together and compose all the input routines together in one shot. (Note that the variables in the above code (v1, v2) represent inputs to be received from the remote server -- all outputs are packaged into the clause expressions themselves and are effectively literals.)
Have you considered using arrows instead? -- brandon s. allbery [solaris,freebsd,perl,pugs,haskell] [EMAIL PROTECTED] system administrator [openafs,heimdal,too many hats] [EMAIL PROTECTED] electrical and computer engineering, carnegie mellon university KF8NH _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
