As limited as my parser is, it *can* handle the above. The following would
work: "drop knives" (drop all knives), "drop knife" (drop one knife), "drop
three knives" (drop three knives), "drop three knife" (drop the third knife).
Unfortunately "drop knive" would drop one knife, and "drop knifes" would drop
all knives. I use "everything" to represent everything you are carrying;
"all" is used only in the context "drop all knives" (which you might as well
use "drop knives" for, now that I think about it).

This is something my parser couldn't handle.

Nope I have two separate glove objects. "trousers" are a pain though, although
you could type "get one pair of trousers".

My parser can handle "torches" rather than "torch", but it was a bit hacky to
add.
