There exist other tools using the @ syntax such as [jsdoc](http://usejsdoc.org/). So far I haven't had any problem mixing the two, but it seems a bit risky to mix them anyway. Is there a way to manage this situation? Could it be possible to support overriding the directive symbol to ensure compatibility? For instance configuring preprocess to use a # instead of @ would solve the problem for people already using jsdoc.
