I am working a reflection / introspection library (dynamic / at runtime, as
opposed to compile time with template and mixin).
Now I can create PropertyInfo classes for property with very little code
and it all works well.
I'm hitting a problem, trying to register all property of my class

I am creating a struct that I want to use as dictionary (associative array)

Initially it was a class and I overrode toHash and opCmp.

override toHash anymore!
How can I make it a good dictionary key?

int main(string[] argv)
{
A a;
SlotDelegate x= a.DIT;
SlotDelegate[] _slotDg;
_slotDg.remove(x);
There is a remove() method in std.algorithm!I even got asked why I was
reimplementing it!
(well, because I didn't know it existed hey!)
works fine with, say, int...
but not with delegate!
associative array will solve the problem indeed.. (I hope) but they use way
more memory!

Cast it. The result will be null if the cast fails.

Add a pair of parentheses to the first overload to add an empty template
argument list – currently, template and non-template functions can't be
overloaded.
I have a MemberDesc class which describe a class's members.
I fill it with a template method like that (with GETTER and SETTER some
other templated method I wrote)
=
MemberDesc MEMBER(T, string memberName)()
{
TypeInfo ti = typeid( typeof(__traits(getMember, T, memberName)) );

Also, std.string.repeat has been scheduled for deprecation. You should use
