I think you misunderstand me: I wanted to avoid the recompilation step 
when adding a breakpoint, that's all.  The interface would be exactly 
the same.  You're right, the idea of using GHCi as the interactive 
debugger is absolutely key: only GHCi has full information about the 
program, so anything else would be a compromise.
