in_files = [] &= help "CVS files with data to visualise" &= args &= typ "FILES"
This is invalid because args and help don't mix, but you get the error:
System.Console.CmdArgs.Implicit, unexpected flag (args/argPos): Flag_ {flagField = "in_files", flagFlag = CVS files with data to visualise, flagExplicit = False, flagGroup = Nothing, flagEnum = Nothing}
That's horrible, and misses the essential parts.
As another example, if you make the help field an unknown type, for example Text, you get the error message:
System.Console.CmdArgs.Implicit, unexpected flag (help): Data.Text.Internal.Text
It doesn't say that its an unexpected type, or that the flag is expected but the type is not.
