Subject: Provide todo function
X-Git-Tag: otter-1.1.0~305
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=9f1ef7773717dd7fe6d92e187d587c407fae5f94;p=otter.git

Provide todo function

Using the todo!() macro in fehler-annotated functions generates
annoying dead code warnings.

And, this will fail to build in release mode - yay!
