Variable can only store one value instead of full list?

[linonetwo]

Just see the first part, import title list should be a list

debug log also say it is a list. But when rendered with {{{ [<importTitles>] }}} it only render first value!

\whitespace trim
<$let importJson={{{ [{$:/Import}] +[debug-log:imp-json[]] }}}>
	JSON length: {{{ [<importJson>length[]] }}} bytes<br/>
	<$let importTitles={{{ [<importJson>jsonindexes[tiddlers]] +[debug-log:imp-titles[]] }}}>
		import title list: {{{ [<importTitles>] }}}<br/>
		<$let importTypes={{{ [<importTitles>] :map[<importJson>jsonget[tiddlers],<currentTiddler>,[type]] +[debug-log:imp-type[]] }}}>
			import type list: <<importTypes>><br/>
			<$list filter="[all[shadows+tiddlers]tag[$:/tags/ImportOptions]]" variable="importOption">
				<$let condition={{{ [<importOption>get[condition]] +[debug-log:imp-cond[]] }}}>
					<$let hasMatch={{{ [<importTypes>subfilter<condition>limit[1]] +[debug-log:imp-match[]] }}}>
						importOption: <<importOption>> | hasMatch: <<hasMatch>><br/>
						<$list filter="[<hasMatch>!is[blank]]" variable="ignore">
							<div class="tc-import-option">
								hit type: {{{ [<importTypes>subfilter<condition>] }}}<br/>
								<$transclude tiddler=<<importOption>>/>
							</div>
						</$list>
					</$let>
				</$let>
			</$list>
		</$let>
	</$let>
</$let>

Oh, I see, availabe in 5.4.0, otherwise it would feel like a bug.

Multi-Valued Variables

[New in v5.4.0](http://127.0.0.1:8080/#Release%205.4.0) The $let widget also allows [multi-valued variables](http://127.0.0.1:8080/#Multi-Valued%20Variables) to be set in one operation to the complete list of results obtained from evaluating an attribute.

Almost all operations that work with variables only consider the first item in the list. Using round brackets instead of angle brackets around the variable name gives access to the complete list of results. For example:

<$let varname={{{ [all[tiddlers]sort[]] }}}>
<$text text={{{ [(varname)] +[join[-]] }}}/>
</$let>
