I think you'll find yourself pressed by the group to make performance high
and to make sure it works well in edge cases. These things are often what
makes the difference between a library being widely used and being widely
ignored. I hope you'll be willing to rise to the challenge. The problem with
a library that is dreadfully obscure and unhelpful near its limits is that
experienced programmers know they will eventally enter that territory,
whether or not that is their intention ;)
