merge precondition message: Constructor alias

[aryairani]

Constructor alias

Each naming of a decl may not have more than one name for each constructor, within the decl's namespace.

Alice's branch:

unique type Foo = Bar

project/alice> alias.term Foo.Bar Foo.some.other.Alias

  Done.

Bob's branch:

bob : Nat
bob = 100

project/alice> merge /bob

  On project/alice, Foo.Bar and Foo.some.other.Alias are
  aliases. Every type declaration must have exactly one name for
  each constructor.

---

Maybe something like:

Sorry, I wasn't able to perform the merge:

On project/alice, the Foo type has some constructors with multiple names, and I can't yet perform a merge in this situation:

Foo.Bar
Foo.some.other.Alias

Foo.Baz
Foo.some.other.other.Alias

Please delete all but one name for each constructor, and then try merging again.
