What I want is gdb for GHC :-) Perhaps another build (like profiling vs
optimizer), and when you press ^C, the ghcdb> prompt comes up :-)
I did at one point want to look at providing a Java style reflection
on polymorphic objects, towards having a non-evaluating print command
at the gdbdb prompt. If anyone is interested in helping me flesh this
out, then please email me.
I wonder if the Cost Center Stack idea can be combined some debugging
concepts, giving an approximation to a stack dump, and you can
print (using a non evaluating print) the stack?
