<p>As already mentioned a couple times the rules can be simplified by disallowing text after and before the starting/leading delimiters.</p>
<ol>
<li><p>Allow single line tripled string <code>"""text"""</code></p></li>
<li><p>Multi-lined text should always be between the delimiter lines. Therefore there is no need for an implicit leading new line or something like <code>"""\</code>. The trailing new line is the artifact of the rule #3.</p></li>
<li><p>Each line in between the delimiter lines produces an implicit new line if not disabled with an explicit backslash at the end of that line. (Last line produces the mentioned artifact in #2.)</p></li>
<li><p>The backslash is also used for trailing precision if needed, however the cost is that the implicit new line is disabled and one would need to write <code>\n\</code>.</p></li>
<li><p>The closing delimiter determines the indent for the current multi-line string literal, by calculating its indent-prefix from the start of that line to the delimiter itself.</p></li>
<li><p>Each line in between the delimiters is stripped exactly like the calculated indent-prefix in #5. If it’s not possible, because of a mismatch of the spacing characters or a non-spacing character was found before the algorithm finished stripping the current line, a warning is emitted to fix the indent. (This rule covers literally everyones indent preferences, because it should not care if the ident is using spaces only, tabs only or a mix of them.)</p></li>
<li><p>#5 and #7 also allows easy leading spacing precision, which was a tedious approach with continuation quotes.</p></li>
</ol>
<p>I think I pretty much covered everything here now. </p>
<p>Let me know if I missed something.</p>

simpler algorithm or even accommodating more styles. Moreover, a
user who wants a trailing or leading newline merely types an extra
one if there is newline stripping, so no use cases are made
difficult, only a very common one is made more
ergonomic.</span></div>
