Thanks Simon, I will be looking into these asap. I'm taking a plane
back home tomorrow morning after some weeks abroad, so it might take me
a few days to catch up.

Hi Pepe,
I played around with breakpoints a little today, they seem to work
pretty well - nice going! I discovered a few minor issues that you
might be able to clear up:
- I can't seem to set a breakpoint on 'main'. In fact, in a file that
contains only 'main', I get:
*Main> :break add Main 1
*** Exception: Module main:Main was not loaded under debugging mode.
Enable debugging mode and reload it
even though I have -fdebugging turned on.
This might be due to breakpoint coalescing. If there are no local
bindings at a site, the breakpoint is not inserted at instrumentation
time.
And there is a possible explanation for the error message. It might be
that in a file with no breakpoints at all, ghci erroneously reports
that the file was not loaded under debugging mode, when in fact it was.
Should we disable this form of coalescing to minimize end user
confusion, or include a bold disclaimer in the manual and/or the error
message?
I don't have a preference for how to do it, but I definitely think the error
message shouldn't lie about whether the file was loaded with -fdebugging, and it
should definitely be possible to set a breakpoint on Main.main. If you don't
have time to do this right now, could you file a ticket and milestone it for 6.8?
Cheers,
Simon
