if(usr.haskey == 1)
usr.verbs+= /mob/verb/Attack

Gads, I would hope not like that.
If you're using vars that have values of 1 or 0 most of the time, leave out the ==1. If for some reason your truth value were ever different, ==1 would fail. Just putting the variable in if() says: If it is not null, not 0, and not an empty string (""). It's simpler, and it's broader in meaning.

My C++ teacher would shoot you for recommending that :p

I agree with you on the issue but he says it's "bad style." He's a Java adict where you can't even use something like:
if(haskey)

Every test statement HAS TO evaluate as boolean. He seems to think this is superior...

In Java I can understand the need for a test to be boolean. However, if one were to translate my recommendation to Java, I'd basically be saying he should test if(haskey!=0) instead of if(haskey==1). Basically that's because, as C observes well, if you're testing something against a specific value, 0 is usually the "safest". Also, most CPUs have a "zero" flag, so tests like if(var!=0) can usually be boiled down to a simpler instruction and operate marginally faster than if(var==1).
