Accumulate to String does not take Strings

[lu-zero]

I'm probably missing something but I couldn't figure out a saner way to use escaped to produce a string with unescaped values.

I used repeat_till with it and I stumbled upon Accumulate not able to directly collect strings to strings.

If that's the case I have a patch to add Cow and String ready.

Seems reasonable to add those
