## Functions on Sequences

any* seq_concat(any*, ...)

seq_concat is a variadic function: it can have any number of arguments. It simply evaluates its arguments (if any) in the order they are listed in the argument list, and concatenates the sequences returned by these arguments.

In addition to the above there are also the following aggregate functions on sequences. They are described in the Sequence Aggregate Functions section.

- long seq_count(any*)
- number seq_sum(any*)
- number seq_avg(any*)
- any_atomic seq_min(any*)
- any_atomic seq_max(any*)
