<p>In the multi-lined version of that literal, the starting delimiter does only one job: “look I’m gonna provide a multi-line string in between me and the closing delimiter”. That’s it’s only job. (Not yet officially proposed, nor it’s in the current toolchain.)</p>
<p>The closing delimiter however covers the leading precision and the indent of the current literal. However this is partly visible for a literal that fully fits onto your screen. (That’s already included in current toolchain.) </p>
<p>The trailing precision is covered by the backslash (because it’s visible and intuitive for the developer), otherwise all whitespace characters are stripped at the end and a new line character is implicitly added to that line. (Not handled in the current toolchain.)</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>
