A given page with <nowiki>{{subst:PageA}}</nowiki>, when substed on PageB
returns the wikicode of PageA.

You can also see it if you call on a page "Please
<nowiki>{{subst:Template}}</nowiki>" and then {{subst:Template}} on another
page, as it becames <nowiki>[[Template:Template]]<!-- WARNING: template loop
detected --></nowiki>

You can use <nowiki>{{subst:</nowiki>PageA<nowiki>}}</nowiki> or
<nowiki>{{</nowiki>subst:PageA<nowiki>}} as workaround.
