:: Bool -> a -> a -> a -package:if
if-then-else as function.
Example:
if' (even n) "even" $
if' (isPrime n) "prime" $
"boring"
The same as
if', but the name is chosen such that it can be
used for GHC-7.0's rebindable if-then-else syntax.
for support of if .. then .. else
RebindableSyntax splats this, and I'm not sure where it exists in GHC
land
Because of RebindableSyntax, this is necessary to enable you to use
if-then-else expressions. No need to call it directly.
Definition of
ifThenElse for use with RebindableSyntax
Hang on the
True case of
bool.
onTrue b f t = bool f t b
Hang on the
False case of
bool.
onFalse b t f = bool f t b
Same as
bool, except the
Bool comes before the case
functions.
Equivalent type signature:
boolL :: forall r. Analysis Bool r
The implementation is just:
boolL = gcase
