String.raw can't represent all strings

For reference, the only things that can't be represented in with String.raw are:

Backslash as last char
- String.raw`\` is a syntax error, it thinks you're escaping the closing `.
- String.raw`\\` will output \\, not \.
Interpolation sigils anywhere
- String.raw`${` is another syntax error, it thinks you're trying to interpolate but you don't have the expression and closing }.
- String.raw`\${` and String.raw`$\{` both contain a backslash in the output
Backticks anywhere – String.raw``` is another syntax error, that's actually 2 tagged template literals with the second one missing its closing `.
