I suspect that the function recursion composition I have used is not working very well, so I'm trying to learn how to use the debugger to understand what is going on, except I don't really understand the output of the GHCi debugger or what is going on very well. I have a main function called 'Analysis' in a library that analyzes a string. I've used :break Analysis and then called :trace and then repeatedly typed :continue, but there are a number of steps between one continue and the next return-and-call of output that I'm not sure I understand. Suggestions on better debugging methods, or even how to fully understand this output, would be very helpful. Thanks in advance.
For pure functions, debug [1] is Godsent. [1] https://hackage.haskell.org/package/debug
