Incompatible with recent compilers

[0xEAB]

Unfortunately this library doesn’t work with recent D compilers.

In my case it’s the following error message:

/home/elias/.dub/packages/concepts-0.0.8/concepts/source/concepts/implements.d-mixin-27(39,32): Error: `;` expected
/home/elias/.dub/packages/concepts-0.0.8/concepts/source/concepts/implements.d-mixin-27(39,33): Error: declaration expected, not `(`
../../source/oceandrift/db/dbal/driver.d(230,33): Error: template instance `concepts.implements.implements!(SQLite3, DatabaseDriver)` error instantiating
../../source/oceandrift/db/sqlite3.d(185,15):        instantiated from here: `isDatabaseDriver!(SQLite3)`
../../source/oceandrift/db/sqlite3.d(185,1):        while evaluating: `static assert(isDatabaseDriver!(SQLite3))`

for roughly this code:

interface DatabaseDriver { /*…*/ }
enum bool isDatabaseDriver(T) = implements!(T, DatabaseDriver);

final class SQLite3 : DatabaseDriver { /* … */ }
static assert(isDatabaseDriver!SQLite3);

I venture to provide a reduced code sample for reproduction because the unittests of this library fail as well, and are probably a handier thing to work with anyway:
