However, since the JEP's goal is to allow copy-paste of arbitrary text
without interpretation, I think the RawSP trick of assigning meaning
to whitespace is out of place. To most people, the raw string literal:
` and `
denotes a perfectly good five-character string that will probably be
inserted between two other strings. Explaining that, no, it's really a
three-character string will not be popular.
+100. The RawSP trick is clever, but too much so. There are ample
simpler approaches for beginning/ending with BT:
String s = BACKTICK + `a raw string` + BACKTICK;
String s = `` `a raw string` ``.trim();
These move the cognitive load on the user to the corner case, rather
than landing it on the general case.
