The take and skip functions on the Seq module raise an error when bounds are exceeded. I suggest the following safe alternatives:
// Safely skip n elements of a sequence, and return the rest.
trySkip : count:int -> source:Seq<'T> -> Seq<'T>
// Safely take n elements from the beginning of a sequence, skip the rest.
tryTake : count:int -> source:Seq<'T> -> Seq<'T>
The suggested functions operate in a similar manner to their link equivalents which don't raise errors when bounds are exceeded.
If this suggestion is accepted it would make sense to implement these functions for List and Array also.
