Nuprl Lemma : return-class-val
∀[Info:Type]. ∀[x:Top]. ∀[es:EO+(Info)]. ∀[e:E]. return-class(x)(e) ~ x supposing ↑e ∈b return-class(x)
Proof
Definitions occuring in Statement :
return-class: return-class(x),
eclass-val: X(e),
in-eclass: e ∈b X,

es-E: E,
assert: ↑b,
uimplies: b supposing a,
uall: ∀[x:A]. B[x],
top: Top,
universe: Type,
sqequal: s ~ t
