+ "The Fowler-Noll-Vo checksum algorithm is another simple and fast checksum. It comes in 32, 64, 128, 256, 512 and 1024-bit versions, each in 1 and 1a variants. The 1a variants tend to produce a slightly better result. See http://en.wikipedia.org/wiki/Fowler_Noll_Vo_hash for more details."

+! I couldn't find any test vectors for 128, 256, 512, or 1024 versions of FNV1 hashes.
+! So, just to check that your maths works the same as my maths, here's a few samples computed on my laptop.
+! So they may be right or wrong, but either way, them failing is cause for concern somewhere...

"The " { $vocab-link "unicode.breaks" "unicode.breaks" } " vocabulary partially implements Unicode Standard Annex #29. This provides for segmentation of a string along grapheme and word boundaries. In Unicode, a grapheme, or a basic unit of display in text, may be more than one code point. For example, in the string \"e\\u000301\" (where U+0301 is a combining acute accent), there is only one grapheme, as the acute accent goes above the e, forming a single grapheme. Word breaks, in general, are more complicated than simply splitting by whitespace, and the Unicode algorithm provides for that."

+"Rational numbers represent " { $emphasis "exact" } " quantities. On the other hand, a floating point number is an " { $emphasis "approximate" } " value. While rationals can grow to any required precision, floating point numbers have limited precision, and manipulating them is usually faster than manipulating ratios or bignums."

The first approach creates a new sequence of the same type as the input, which does not share storage with the underlying sequence. This takes time proportional to the number of elements being extracted. The second approach creates a " { $emphasis "slice" } ", which is a virtual sequence (see " { $link "virtual-sequences" } ") sharing storage with the original sequence. Slices are constructed in constant time."
+$nl
+"Some general guidelines for choosing between the two approaches:"
+{ $list
+ "If you are using mutable state, the choice has to be made one way or another because of semantics; mutating a slice will change the underlying sequence."
+ { "Using a slice can improve algorithmic complexity. For example, if each iteration of a loop decomposes a sequence using " { $link first } " and " { $link rest } ", then the loop will run in quadratic time, relative to the length of the sequence. Using " { $link rest-slice } " changes the loop to run in linear time, since " { $link rest-slice } " does not copy any elements. Taking a slice of a slice will “collapse” the slice so to avoid the double indirection, so it is safe to use slices in recursive code." }
+ "Accessing elements from a concrete sequence (such as a string or an array) is often faster than accessing elements from a slice, because slice access entails additional indirection. However, in some cases, if the slice is immediately consumed by an iteration combinator, the compiler can eliminate the slice allocation and indirect altogether."
