Module Alias Namespace In Alloy 4 -


lets following:

open util/ordering[a] open util/ordering[b]

what value ordering/first have? undefined? need use module aliases disambiguate?

yes, should use aliases, e.g., did below

open util/ordering[a] orda open util/ordering[b] ordb  sig a{} sig b{}  sig c {    firsta: a,    firstb: b } {    firsta = orda/first    firstb = ordb/first }  run {one c}
