I've often thought about how tricky/silly it must be to work in some domains using tools of other domains.

For example, I work with cartographic data and the darn mathies and programmers stole all our words. So I end up performing a map on a Map of maps. Or managing vector of vector layers. Naming is hard but this is ridiculous.

Using mockup tools to make mockup tools probably has its own set of ridiculous collisions.
