From a programmatic and practical point of view, I don't understand why would someone want to put a bang in the middle of a request or within a word.

Basically you have your request and you add a criteria on it, not in it.

It's like ordering at a restaurant : you wouldn't say "I'll have a burger to take away, some fries and a coke". You either specify how you'll have your order before or after the actual order. And you don't create a new word like "a cokedinein".

Furthermore, I want Kagi to be able to reply to the request "how do the !g bang works?"; if I want something else to reply, I'll add the relevant bang around my request.

Or I'm missing something?
