Package Flags

haskell98_fragment

 (off by default)

Sacrifice generic deriving, the NFDataPDyn module, and a couple functions from the PatAlg module, in exchange for true Haskell98 conformance (portability). You need to set PARALLELISM_EXPERIMENT, USE_WW_DEEPSEQ, USE_SOP, and NFDATA_INSTANCE_PATTERN to False if you set HASKELL98_FRAGMENT to True. (One thing it insists on is -XPatternGuards, although this could be relieved in the obvious way...)

parallelism_experiment

 (on by default)

We can selectively use par instead of seq, which is interesting.

just_alias_gseqable

 (on by default)

The SOP generic function is probably more performant, anyway! (This will be forced False if HASKELL98_FRAGMENT is True.)

use_ww_deepseq

 (on by default)

Depend on deepseq and deepseq-generics, to provide conditional deep forcing. This is optional.

warn_pattern_match_failure

 (off by default)

For NFDataP, if a pattern match fails a warning is output to stderr.

use_sop

 (on by default)

Use the generics-sop package instead of GHC.Generics (in GNFDataN) and instead of SYB (in NFDataPDyn). If USE_SOP is False, and NFDataPDyn, GNFDataP, and GSeqable modules will not be available. Also, if USE_SOP is False, then JUST_ALIAS_GSEQABLE must be False (this is not done for you; the language of Cabal flags makes it hard to write such logic, probably by design!...).

nfdata_instance_pattern

 (on by default)

A flag to assist debugging, affecting a few modules.
