Sequence f, then fa, combining their results by function
application.
Sequence f, then fa, combining their results by function
application.
NB: with respect to apply2 and all other combinators, as well
as scalaz.Bind, the f action appears to the *left*. So
f should be the "first" F-action to perform. This is in
accordance with all other implementations of this typeclass in
common use, which are "function first".

A commutative operation which chooses nondeterministically to obtain
a value from either a or b.
A commutative operation which chooses nondeterministically to obtain
a value from either a or b. If a 'wins', a 'residual' context
for b is returned; if b wins, a residual context for a is
returned. The residual is useful for various instances like Future,
which may race the two computations and require a residual to ensure
the result of the 'losing' computation is not discarded.
This function can be defined in terms of chooseAny or vice versa.
The default implementation calls chooseAny with a
two-element list and uses the Functor for F to fix up types.
A commutative operation which chooses nondeterministically to obtain
a value from any of the elements of as.
A commutative operation which chooses nondeterministically to obtain
a value from any of the elements of as. In the language of posets, this
constructs an antichain (a set of elements which are all incomparable) in
the effect poset for this computation.

Nondeterministically gather results from the given sequence of actions.
Nondeterministically gather results from the given sequence of actions.
This function is the nondeterministic analogue of sequence and should
behave identically to sequence so long as there is no interaction between
the effects being gathered. However, unlike sequence, which decides on
a total order of effects, the effects in a gather are unordered with
respect to each other.
Although the effects are unordered, we ensure the order of results
matches the order of the input sequence. Also see gatherUnordered.
Nondeterministically gather results from the given sequence of actions to a list.
Nondeterministically gather results from the given sequence of actions
to a list. Same as calling reduceUnordered with the List Monoid.
To preserve the order of the output list while allowing nondetermininstic
ordering of effects, use gather.
