version constant interpolation in module descriptor

[gavinking]

Mentioned here by @FroMage, it would be nice to be able to do stuff like this:

module my.example "1.0.0" {
    value javaVersion = "8";
    value ceylonVersion = "1.3.3-SNAPSHOT";

    import java.base javaVersion;

    import javafx.base javaVersion;
    import javafx.graphics javaVersion;
    import javafx.controls javaVersion;

    import ceylon.collection ceylonVersion;
    import ceylon.file ceylonVersion;
}

This is already basically working, but I think I need to add a ImportModuleListScope.

I wonder if we should have some predefined constants, for example ceylonVersion, holding the version of the compiler.

Well we already have that one as language.version, so it seems like allowing that would be cleaner…

On the other hand, that might suggest that changing the ceylon.language version via overrides should automatically change those imports as well (we probably don’t want that) and that you can use other String values from other modules as well (we definitely don’t want that).

Well, anyway, this is done now, closing this issue.

Very cool!
