Problem: In order to create shorthand or stable links to sections, editors create fragment IDs (aka anchors) that point to sections that differ from the visible headings. This can be done using {{anchor}}, as in == {{anchor|Anchor}} Heading ==, or its substituted form, == <span id="Anchor"></span> Heading ==, but the first results in bad section links—as in /* {{anchor|Anchor}} Heading */, which shows up as →{{anchor|Anchor}} Heading—while the second is less self-evident as to what it's for, especially to newcomers. Another solution is to put the {{anchor}} or <span>...</span> at the end of the previous section, but this doesn't show up when editing the section (and shows up at the end when editing the previous), which is quite confusing.
Proposed solution: We need a way to add fragment IDs inside section headings that 1) communicates clearly what it's doing and 2) doesn't affect section links. E.g. a parser function like {{#sectionanchor:Anchor name}} that can be used anywhere inside a section and results in <span id="Anchor_name"></span> prepended at the top of (or inserted before) the nearest Hn element before the function call.
