Sure, I can give an example. I'm not going to suggest that it'd win
any awards, but:<br>
<br>
By restricting multiline literals to begin and end on distinct
lines, the core team has established an interesting property.
Namely, "literals" are delimited horizontally while """literals"""
are delimited vertically.<br>
<br>
To enable hard wrapping, permit continuation of literals by
apposition of consecutive literals. That is, "Hello, " "world!"
would be equivalent to "Hello, world!". This single rule can be
applied to either kind of string literal. That is:<br>
<br>
let a =<br>
"Hello, "<br>
"world!"<br>
<br>
let b =<br>
"""<br>
Hello,<br>
""" """<br>
world!<br>
"""<br>
<br>
a == b // true<br>
<br>
It certainly permits elided newlines. It is the exact same rule
applied to both types of literals. It preserves code indentation
and does not require single-line string literals to support code
stripping. I leave it to your judgement whether it works "equally
well" and/or is "horrible."<br>

This goes to my question to David Hart. Isn't this an argument for
a feature to allow breaking a single-line string literal across
multiple lines? What makes this a use case for some feature
for _multiline_ string literals in particular?</span></span></div>
</blockquote>
<br></div>
<div>Well, if you're breaking a string across several lines, you
will want indentation stripping too. Are you suggesting we should
also bring that feature to single-line string literals with escaped
newlines?</div>
</div>
</blockquote>
<div><br></div>
<div>No, I am suggesting that whatever design is used for escaped
newlines, if at all possible it should be equally apt for "strings"
and """strings""" such that it will not require indentation
stripping.</div>

<div>Could you share an example of such a design? It doesn't have
