It is a compile-time error to import two or more libraries that define the same name.

// Library 1_Imports_A05_t01_p1_lib.dart:

library("duplicate_library_name");

var foo;

---

// Library 1_Imports_A05_t01_p2_lib.dart:

library("duplicate_library_name");

bar(int x, bool b) { return 0; }

---

// both libraries define the same library name in their respective headers

import("1_Imports_A05_t01_p1_lib.dart", prefix: "P1");

import("1_Imports_A05_t01_p2_lib.dart", prefix: "P2");

main() {
}

Compile-time error should be reported, but is not.

In case this is not an error, please file a co19 bug for test Language/12_Libraries_and_Scripts/1_Imports_A05_t01 and update the issue number in the co19 status file.

The spec says this about the #library tag:

It is a compile-time error if the argument x to a library or resource directive is not a compile-time constant, or if x involves string interpolation.

I see no mention of duplicate library names anywhere in the spec. Gilad, can you please verify?

This is an oversight in the spec. The 0.10 draft will very soon say:

"It is compile-time error to import two different libraries with the same name."

This will allow us to identify libraries by name for reflection and printing, and to experiment with ideas about default prefixes.

I would expect people to use a scalable naming convention a la Java (tm) so that publicly shared libraries have unique names.
