[Haskell-cafe] Convert a function to a string of operators?

[Evgeny Grablyk]

Many thanks for your help! Seems to be what I need. Two more related questions:

Will methods explained here work for boolean expressions?
Is there a way to extract parameter names from function definition to
use them in Show instance? Or should I just use same names everywhere?

In case  that helps, here's the code I need to convert (the code in
where part of solveScheme): http://npaste.de/aKY3cn0xZf/
