Printing type name in static assert

[Martin Cejp]

alias Field = typeof(__traits(getMember, Vertex, fieldName));

const bool normalized = HasAnnotation!(Vertex, fieldName, 
Normalized);
const int fieldOffset = __traits(getMember, Vertex.init, 
fieldName).offsetof;

int i = GetAnnotationInstance!(Vertex, fieldName, Position).pos;

glVertexAttribPointer(i, cast(GLint) numElements!Field, 
TypeToGLEnum!(ElementType!Field),
         normalized ? GL_TRUE : GL_FALSE, Vertex.sizeof, 
cast(void*) fieldOffset);
glEnableVertexAttribArray(i);


I'm starting to like this language :-)
