Thanks. Added!

@s-ludwig anything blocking this? Returning a string happens often enough, s.t. imho it justifies the convenience and also this is just an added bonus as a couple of return types (InputStream and Json are already accepted).

Ping @s-ludwig - I think this is a trivial, non-controversial addition and helps a lot of people as returning string is a frequent use case.

const(char)[] is sufficient here.

Would be nice to add const(ubyte)[] here, too (and change to const(char)[] if adjusted).

Couldn't find a compelling argument against this, especially considering that ubyte[] and char[] are already supported by writeBody in a similar way. Would just be nice to loosen this up to const(char)[] instead of string.

Good idea. Done.
