Syntax

	concat($s1, $s2, ..., $sN)

Description

Merge the given sets or single values into a set. This can be used to add new elements to a set, since sets are otherwise not editable.

If all parts are scalar values, the expression is equivalent to list($s1, $s2, ..., $sN) (see List from single values).

Otherwise the expression is also equivalent to list($s1, $s2, ..., $sN).flatten() (see Flatten).
