Nuprl Lemma : hdf-halt-compose2
∀[X:Top]. (hdf-halt() o X ~ hdf-halt())
Proof
Definitions occuring in Statement :
hdf-compose2: X o Y,
hdf-halt: hdf-halt(),
uall: ∀[x:A]. B[x],
top: Top,

Definitions unfolded in proof :
uall: ∀[x:A]. B[x],
member: t ∈ T,
hdf-compose2: X o Y,
mk-hdf: mk-hdf(s,m.G[s; m];st.H[st];s0),
all: ∀x:A. B[x],
