Thanks, that got me on the right track for an answer!
Using the [tag<currentTiddler>limit[1]]] filter as an outer $list works,
though it resets the currentTiddler variable to the first tiddler that's
tagged with the original tiddler. So, I ended up doing this:
A global Macro (in case I want to use it elsewhere):
\define listTagged(tagName)
<$set name="t" value=<<__tagName__>>><$list filter="[title<t>]">
<$count filter="[tag<t>]" /> Pages tagged with <$macrocall $name=
"tag-pill-body" tag=<<currentTiddler>> icon={{!!icon}} colour={{!!color}}
palette={{$:/palette}} element-tag="""$button"""
element-attributes="""tag='span'"""/>:
<ul><$list filter="[tag<t>]">
<li><$link><$view field="title" /></$link></li>
</$list></ul>
</$list>
</$set>
\end
And then a ViewTemplate to use it:
<$set name="t" value=<<currentTiddler>>>
<$list filter="[tag<currentTiddler>limit[1]]">
<hr />
<$macrocall $name="listTagged" tagName=<<t>> />
</$list>
</$set>
The trick is I used a $set call to save the first currentTiddler value to a
separate variable (t) for use later in the logic.
