yes, yes, yes! definitely! i'll just show my code:
parseCmdline cmdline = do
.....
return$ Just$ Command {
cmd_name = cmd
, cmd_arcspec = arcspec
, cmd_arclist = error "Using uninitialized cmd_arclist"
, cmd_arcname = error "Using uninitialized cmd_arcname"
, cmd_arc_filter = const True
, cmd_filespecs = filespecs
, cmd_added_arcnames = return []
, cmd_diskfiles = return []
, cmd_subcommand = False
, opt_scan_subdirs = scan_subdirs
, opt_add_dir = add_dir
, opt_arc_basedir = arc_basedir
, opt_disk_basedir = disk_basedir
, opt_group_dir = group_dir
, opt_group_data = group_data
, opt_data_compressor = data_compressor
, opt_dir_compressor = dir_compressor
, opt_include_dirs = include_dirs
, opt_indicator = indicator
, opt_overwrite = overwrite
, opt_keep_time = keep_time
, opt_time_to_last = time_to_last
, opt_test = test_files
, opt_keep_broken = keep_broken
, opt_match_with = match_with
, opt_append = append
, opt_recompress = recompress
, opt_noarcext = noarcext
, opt_nodir = nodir
, opt_debug = debug
, opt_cache = cache
, opt_update_type = update_type
, opt_x_include_dirs = x_include_dirs
, opt_match_excluded = match_excluded
, opt_sort_order = sort_order
, opt_find_group = find_group . fiFilteredName
, opt_groups_count = length group_strings
, opt_find_type = find_type . fiFilteredName
, opt_types_count = maximum group_types + 1
, opt_arccmt_file = arccmt_file
, opt_lock_archive = lock_archive
