 Variable width structs (dynamic structs) can accomodate generics and variable width members.  Dynamic structs may extend static structs or other dynamic structs.  By extending a dynamic struct, even if one makes no use of the dynamic members, their struct is automatically a dynamic struct.  These structs offer the least control over memory, and slightly slower call times, but offer the most flexability to the programmer.

+### Core Language
+
+The core language encompases what you would expect from any C-like language:
+- Modules
+- Variables
+- Enums
+- Types
+- Functions
+- Methods
+- Interfaces
+- Scalar Operators
+- Control Flow
+- Anonymous Functions
+- Inline Assembly
+- Interop with C ABI
+
+### Advanced Language Features
+These may depend on support from `libtnsl`, though they are still considered "standard" and any complete implementation of TNSL must include them.
+The table below shows what parts of the standard library must be present for the features to work as designed:
+
+| Feature         | libtnsl - `reflect` | libtnsl - `thread` | libtnsl - `stream` |
+| --------------- | ------------------- | ------------------ | ------------------ |
+| Runtime type reflection | Yes | - | - |
+| Threads | - | Yes | - |
+| Mutex | - | Yes | - |
+| Coroutines | - | Yes | - |
+| Generators | - | Yes | - |
+| Loop over Generator | - | Yes | - |
+| Stream | - | - | Yes |
+| Stream Operators | - | - | Yes |
+| Loop over Streams | - | Yes | Yes |

 Unicode Non-standard 7+1 bit (UN7+1) encoding is a non-standard way to represent any unicode character using a series of 8-bit values.  The first bit in the 8-bit sequence represents if the next 8-bit sequence is included in the character code, the other seven bits are part of the character code.
