====Stream-Buffer:each====
{{luaself|pre=Stream-|:each|args=...}}

Appends an undetermined number of [[#valid|valid]] values to the Buffer object.<ref group="note">This is no different than calling the Stream-Buffer object directly with each item in the {{luaref|expression list}}; however, after noting how numbers and variables (too shy to [[skinny dip]] without parenthesis) could look rather odd swimming fully clothed in a stream of naked strings, this was made for those whose aesthetics prefer {{luaself|pre=Stream-|:each|args=('A',arg,'B',arg2)}} over {{code|lang=lua|Stream{{ndash}}Buffer'A'(arg)'B'(arg2)}}.</ref>

If the above line gives you [[Déjà vu]], that is because it is drawn from {{luaref|mw.html:wikitext|plain=y}}. However, unlike mw.html:wikitext, this does ''not'' stop at the first ''nil'' value.<ref group="note">If you want something like {{code|lang=lua|:wikitext('string1', varName, 'string2')}} such that ''varName'' is shorthand for an {{code|lang=lua|if}} statement that appends ''varName'' and 'string2' when the former is not nil, use {{code|lang=lua|:each('string1', {varName, 'string2'})}} instead.</ref>
