In the beginning my games, I always equip something in the missile slot as soon as possible in order to be able to check the nearby monsters using 't'arget instead of 'l'ook.

Thinking about this, I came to the conclusion that the 'l'ook command would be a lot more usable if it worked in a similar manner. Moreover, I would like to see the behavior extended to not only scroll through monsters but also through all "lookable" features, e.g. doors, traps, altars, etc.
