====Stream-Buffer object====
{{luaself|pre=Stream-|\|args='string'|args2={concat{{ndash}}list}|args3=(var)}}{{anchor|streaming|calling a Buffer:stream}}

Stream-Buffer objects accept only one argument which they append if [[#valid|valid]]. That is, the op is a streamlined version of {{luaself|:_}} sans the ''pos'' and ''raw'' args.

This also exploits {{luaref|named arguments|the syntactic sugar of function calls|y}} to append a series of string literals (and tables) with nothing between them (or only {{luaref|Character class|ASCII space chars|y}} if desired).

For example, both A and B will produce identical strings:

{{#tag:syntaxhighlight|local A = require'Module:Buffer':stream'A string of text may flow'<nowiki />'with nothing between each string' 'or perhaps only a space'
	'or even tab and line-break characters'<nowiki />'and continue to append individually'<nowiki />'for use with a joiner'
local B = require'Module:Buffer':_'A string of text may flow':_'with nothing between each string' :_ 'or perhaps only a space'
	:_'or even tab and line-break characters':_'and continue to append individually':_'for use with a joiner'
mw.log(A==B, A:_str' ')
true	A string of text may flow with nothing between each string or perhaps only a space or even tab and line-break characters and continue to append individually for use with a joiner
