A semigroupoid is any set A with a partial binary associative operation (partialOp), which is associative in the
following sense: if f,g,h are elements of the semigroupoid such that either:
(i) f |+|? g is defined and g |+|? h is defined
(ii) f |+|? g is defined and (f |+|? g).get |+|? h is defined
(iii) g |+|? h is defined and f |+|? (g |+|? h).get is defined
then all of f |+|? g, g |+|? h, (f |+|? g).get |+|? h, f |+|? (g |+|? h).get are defined and
((f |+|? g).get |+|? h).get = (f |+|? (g |+|? h).get).get
