This package implements generic algorithms oriented towards the processing of
sequences. Sequences processed by these functions define range-based
interfaces.  See also $(LINK2 std_range.html, Reference on ranges) and
$(WEB ddili.org/ders/d.en/ranges.html, tutorial on ranges).

Many functions in this package are parameterized with a $(GLOSSARY predicate).
The predicate may be any suitable callable type
(a function, a delegate, a $(GLOSSARY functor), or a lambda), or a
compile-time string. The string may consist of $(B any) legal D
expression that uses the symbol $(D a) (for unary functions) or the
symbols $(D a) and $(D b) (for binary functions). These names will NOT
interfere with other homonym symbols in user code because they are
evaluated in a different context. The default for all binary
comparison predicates is $(D "a == b") for unordered operations and
$(D "a < b") for ordered operations.

Example:

----
int[] a = ...;
static bool greater(int a, int b)
{
    return a > b;
}
sort!(greater)(a);         // predicate as alias
sort!((a, b) => a > b)(a); // predicate as a lambda.
sort!("a > b")(a);         // predicate as string
                           // (no ambiguity with array name)
sort(a);                   // no predicate, "a < b" is implicit
----
