 Allows passing null pointers to UDT members of APIs/interfaces. The equivalent behavior in VBx is to declare them `As Any` and then pass `ByVal 0` at call sites.

 ## CType(Of \<type\>)
 
 The `CType(Of <type>)` operator specifies an explicit intent to cast one type to another. This can be used for casting `LongPtr` (or `Long` on 32bit/`LongLong` on 64bit) to a custom user-defined type, with or without making a copy of it, depending on the usage. This allows not just for casting directly without a `CopyMemory` call, but also, setting the members of a UDT represented only by a pointer, without copying memory back and forth.

 This will print `4`. Free standing use and nesting is also allowed; the above will print `4`. While the examples here are local code only, this is particularly useful for APIs, where you're forced to work with pointers extensively.

 ## Len/LenB(Of \<type\>) Support
 
 The classic `Len` and `LenB` functions can now be used to directly get the length/size of a type, both intrinsic and user-defined, without needing have declared a variable of that type. For instance, to know the pointer size, you can use `LenB(Of LongPtr)`.
