"break" in the sense that they're now registered but won't have an
appropriate compiler installed.

Right.

If we could at least list the names (and commands to reinstall )
packages that are about to break (all haskell-* on the system), that
might be nice.

Essentially, something like:

    "WARNING: the following packages will need to be reinstalled:
        pacman -Qs haskell-

    local/haskell-xauth 0.1-1
        A binding to the X11 authentication library
    local/haskell-xcb-types 0.5.1.1-1
        Parses XML files used by the XCB project
    local/haskell-xhtml 3000.2.0.1-1
        An XHTML combinator library
    local/haskell-xml 1.3.4-1
        A simple XML library.
    local/haskell-xml-basic 0.0.1-1
        Basics for XML/HTML representation and processing
    local/haskell-yogurt 0.3-1
        A MUD client library
    local/haskell-zip-archive 0.1.1.3-1
        Library for creating and modifying zip archives.
    local/haskell-zlib 0.5.0.0-1
        Compression and decompression in the gzip and zlib formats
    local/haskell-zoneinfo 0.3-1
        ZoneInfo library.
    ...
  
    etc...

?

OK.
