    d/dx*int(f(x))dx = f(x)

      and int [f(x)dx] = ?

      It equals COUNT, goddammit.

    Γ ⊢ ν(α ∈ σ) M : τ & α ∉ ftv(τ)

      I don’t think that’s well-formed, not even in the ⊢WTF system.

        If it helps, ‘ftv’ is an abbreviation for “free type variable.”

          …and next you’ll be telling me that Γ is a set of typing assumptions, M is a term and τ is a type, but I don’t know what that & is doing in there.

            Yeah, that is one of the problems when you’re looking at that shit in a paper and trying to figure out how to translate it into Twelf.

          Anyway, I’m curious what type system that’s from; that’s a tough thing to Google (though I’m amused that I wrote one of the top hits for “ftv(τ)”).

            It’s in here somewhere.

    cute galore.

    when i was a little person i used to think the count was related to us counters :P
