Could you share an example of such a design? It doesn't have to be something you'd be happy to have in the language; it just needs to fit the following criteria:

* Permits non-significant hard-wrapping in a string literal.

* Works equally well with single and triple string literals.

* Preserves code indentation, but does not require single string literals to do indentation stripping.

* Is not horribly inconvenient.
