Variant used as an educational tool

[bjorngudis]

Hi guys,
I'm new here, but have played Angband off and on since the 90s.
I was just wondering if anyone knows if someone has made a variant which can be used as an educational tool?
I was thinking something like that anytime you make a first melee attack, fire a first arrow, cast a spell or try to open a chest the player would be asked a question. The question would be based on an array where the teacher, parent or player would put in the question / answers.
A successful answer would give a large boost to the success chance and/or increase damage from the attack, incorrect one virtually destroys the chance of success.

Just curious if something like that has been done?
