future.


I'd say clear should be @disabled in Appender for non-mutable 
data.

What's wrong with format() from std.string?



Thanks, that was the function I was looking for. I just expected it to
be in std.format (and I also looked in std.stdio).


Seems std.string.format is missing positional arguments..
