Pointer Query Operations

FluentQuery supports the following operations when querying pointers from a container (eg, a TList, or a TList<Pointer>):

Operation	Bound	Unbound	Terminating	Description
First	Yes	Yes		Enumerate the first pointer, ignoring the remainder.
From		Yes		From allows you to specify the source of the data you are querying. It is also From which transforms an Unbound Query into a Bound Query.
IsAssigned	Yes	Yes		Enumerates non-nil pointers.
Skip	Yes	Yes		Skip will bypass the specified number of pointers from the start of the enumeration, after which it will enumerate the remaining pointers as normal.
SkipWhile	Yes	Yes		SkipWhile will bypass pointers at the start of the enumeration while the supplied Predicate evaluates True. Once the Predicate evaluates false, all remaining pointers will be enumerated as normal.
Take	Yes	Yes		Take will enumerate up to the specified number of pointers, then ignore the remainder.
TakeWhile	Yes	Yes		TakeWhile will continue enumerating pointers while the supplied Predicate evaluates True, after which it will ignore the remaining pointers.
Where	Yes	Yes		Filter the pointers enumerated to only those that evaluate true when passed into the supplied Predicate
