bolts meta programming library version 1.0.0 - including the from idiom

[aliak]

I've been using a set of meta tools for a while now, so decided 
to release it as 1.0.0 with a few enhancements chucked on.

Two of the highlights are the non-eponymous "member" and "iz" 
templates, which are shown below with some code. The library also 
includes the "from" template because I tend to use that 
everywhere.

Current issues include:

1) that I'm not completely sure about the behaviour of the 
copy-constructor traits - I've decided to pretend post blots 
don't exist and marked the library as requiring dmd frontend 
2.086 and above.

2) It's an ongoing battle with D to normalize parameters because 
traits return tuples, or string, or tuples of strings, or alias 
tuples, etc. And some traits take symbols, while others take 
strings, etc. One of the goals is to make this library a little 
more consistent and try and keep it that way. I will break things 
to make things consistent (is my intention).

3) Naming - e.g. why are some things in std.meta capitalized 
(i.e. Filter) and others camel-cased with a static prefix - i.e. 
staticMap? What would be the consistent thing to do? I currently 
have a staticZip in there, should it just be Zip?

Some sample code:

unittest {
     import bolts;

     int i;
     class C { void f0() {} int f1(int) { return 0; } }
     static struct S { void f0() {} int f1(int) { return 0; } 
@property void set(int) {} }

     pragma(msg, from.std.allSatisfy!(iz!int.of, 3, 4, int, i)); 
// true
     pragma(msg, from.std.Filter!(isNullable, int*, C, S)); // 
(int*, C)

     // Member functions
     pragma(msg, memberFunctionsOf!S.asStrings); // tuple("f0", 
"f1")
     pragma(msg, memberFunctionsOf!C.asAliases); // tuple(f0, f1, 
toString, toHash, opCmp, opEquals, factory)

     // member template
     pragma(msg, member!(S, "f0").exists); // true
     pragma(msg, member!(S, "f0").protection); // public
     pragma(msg, member!(S, "f0").isProperty); // false
     pragma(msg, member!(S, "set").propertySemantics); // 
PropertySemantics.w

     // iz template
     static struct OldS {
         this(this) {}
     }
     static struct NewS {
         this(ref NewS s) {}
     }
     pragma(msg, iz!S.triviallyCopyConstructable); // yes
     pragma(msg, iz!OldS.triviallyCopyConstructable); // no 
because post-blit
     pragma(msg, iz!OldS.copyConstructable); // no because post 
blit

     pragma(msg, iz!NewS.copyConstructable); // yes
     pragma(msg, iz!NewS.nonTriviallyCopyConstructable); // yes

     // meta fun with packs and zip
     {
         alias a = AliasPack!(1, 2, 3);
         alias b = AliasPack!(4, 5, 6);
         alias c = AliasPack!(7, 8, 9);

         alias d = staticZip!(a, b, c);

         static assert(d.length == 3);

         static assert(d.Unpack[0].equals!(1, 4, 7));
         static assert(d.Unpack[1].equals!(2, 5, 8));
         static assert(d.Unpack[2].equals!(3, 6, 9));

         static assert(AliasPack!(d.UnpackDeep).equals!(1, 4, 7, 
2, 5, 8, 3, 6, 9));
     }
}
