Comment (by phercek):
Hi, Simon Marlow indicated that the unavailable selector function could be
a bug too here:
http://www.haskell.org/pipermail/glasgow-haskell-
users/2008-November/015879.html
My opinion is that it is a bug, i.e. functions which are not exported from
a module should be available when debugging inside the module where they
are defined (but they should not be available when debugging some other
modules).
In other words (from a debugger user perspective), all identifiers which
are in scope at a break point location should be available in debugger for
use. Of course I see now that there are technicall reasons why non-free
variable identifiers (which are in scope) are not available. In such a
case some workarounds may be done to improve the pain
(http://hackage.haskell.org/trac/ghc/ticket/2737). But do the same
technical reasons apply also to function names too? I hope not.
Maybe the "field selection function not available in debugger" part of
this bug report is a new feature request instead of a bug?
