Is there any way to get a list of the properties and functions provided by a module or class or generic variable in D at runtime?  I've grown quite accustomed to doing the following kinds of exploration in Python.

With in the python interperter I can issue:

> a = some_barely_understood_function()
> dir(a)

 ...or for some new module

> import some_new_module
> dir(some_new_module)

The built in function 'dir' is handy as it prints a list of the members of anything.  Since there are many odd members in D such as "int.min" and "double.max_exp", how can I a list of all members of "int", or "double"?  Right now it feels like I just have to get luckly while searching online for this information.

Thanks

In D there are various traits to do that a compile-time. Like:

There are also the Phobos traits:
