Comment (by duncan):
Replying to [comment:1 igloo]:
> I'd expect a dump command to give data in a lower-level format, e.g.
Show/Read.
Well I don't see that it makes a great deal of difference. We have parsers
and printer functions for both formats anyway. The Read/Show format is
more fragile when it comes to adding fields. The Read/Show format is not
necessarily faster. The non-Read/Show format is easier to read and debug I
think.
> I think the ghc-pkg flags have grown a bit crufty; perhaps we should
rethink them for 6.10?
Yes. For example it is currently extremely hard to find the packages of a
given name in a specific package database. The list and field commands
always search all packages (global, user, explicitly specified).
