The pattern is all about grabbing the results of a very complex process,
and scanning those results to decide on whether or not to do something.
```
<$wikify name="codeIssuesCheck" text={{{ [[Code Issues Template]get[text]]
}}} >
<$list variable="codeIssues"
filter="[<codeIssuesCheck>search-replace:g:regexp[\n],[:NL:]split[:NL:]regexp[Declare
sub]count[]!match[0]]">
''<<menuItemBtn "View Code Issues#️⃣prod">>''
</$list>
</$wikify>
```
The Code Issues Template cobbles together a report from a whole bunch of
complex information. Very complex code that takes a lot of things into
consideration, and no way to create a tidy little filter that just gets a
count of issues for deciding whether or not to show the menu item.
I only want the "View Code Issues" menu to display if there are any
"Declare sub" issues.
