# {{=}} will be converted to a parser function which expands to `=`
# If you have it defined as a Template that expands to something other
# than `=` that will generate a warning and a tracking category, although
# referencing the template explicitly as {{Template:=}} is fine
# regardless of what it expands to. (T91154)
!! test
Using {{=}} when that doesn't expand to "=" should create a tracking category
