Re: Proposal: user defined attributes

[dennis luehring]

i don't get the GC relation here?

all attribute values are static const - because they are type-related 
(static) and read-only, attributes are type orientated not instance 
orientated

@GC.NoScan int value;
@GC this() {}

Compiler Asks library for transformation of unknown @GC
bool library("@GC this() {anything...}") ->

if the library succeeds it would then transform the string and
hand back a lowered mixin to the compiler.

mixin("
this()
{
    auto b = [ __traits(allMembers, D) ];
    foreach( auto a; b) {DO.GC.Stuff...}

    anything...
}
");
