Sönke Ludwig 513729bf59 Enable proper default initialization.
Since @disable this() still leaves an invalid .init open, TaggedAlgebraic.init has now been changed to always contain the .init value of the first specified sub type.

Note that this change is restricted to DMD 2.072 and up, because earlier versions of DMD do not allow postblits or destructors within unions and using a union appears to be the only way to implement this.

Make apply() work for plain values, too.
This provides symmetry between TaggedAlgebraic values and ordinary values.

Add apply() to generically extract the contained value.
See also #3.

- Uses std.conv.to to implement opCast instead of just supporting implicit type conversions
- Adds .toString to make to!string(ta) return the expected result

Sönke Ludwig 96f18356f7 Output a proper error message when using hasType with an invalid type. Fixes #1. 2015-08-27 11:27:57 +02:00
Sönke Ludwig 84d6c8da80 Rename "type" to "kind".
Although there will be situations where the enum names equal the name of the types stored in a TaggedAlgebraic, "type" is often not the right term. It's also possible to define multiple fields of the same type, but with different names. "Kind" is used now as a more generic alternative.

Sönke Ludwig e53ae02ec6 Fix postblit/destructor handling and partially fix compilation on DMD 2.067.1.
Also allow to use a struct instead of a union to pass the fields to TaggedAlgebraic (because union doesn't allow fields with postblit/destructor).
