++ Description:
++ This domain implements "such that" forms
SuchThat(S1, S2): Cat == Capsule where
E ==> OutputForm
S1, S2: SetCategory
Cat == SetCategory with
construct: (S1, S2) -> %
++ construct(s,t) makes a form s:t
lhs: % -> S1
++ lhs(f) returns the left side of f
rhs: % -> S2
++ rhs(f) returns the right side of f
Capsule == add
Rep := Record(obj: S1, cond: S2)
construct(o, c) == [o, c]$Record(obj: S1, cond: S2)
lhs st == st.obj
rhs st == st.cond
coerce(w):E == infix("|"::E, w.obj::E, w.cond::E)
