+# Some Thoughts on Programming Language Design
+
+This is a collection of ideas to look at when inventing new langauges.
+
+## Other Ideas
+
+- The Language pushes abstraction to the limit by not noting any
+  hardware-related issues like memory-allocations, parallelism, heterogenous
+  computer architecture (CPU, GPU, …)
+  - requires a very "intellegent" compiler and a way to describe unknowns like
+    possible inputs, etc. in the language itself
+- Start with assembly but add a very flexible macro system
+
+## Type System
+
+```diff
+# Haskell
+data LinkedList a = Nil | Cons a (Box (LinkedList a))
+data Test = Empty | Blub Int | State { x :: Int, y :: Int }
+# Rust
+enum LinkedList<T> { Nil, Cons(T, LinkedList<T>) }
+```
+
+## Memory Management
+
+- **Drop when out-of-scope**
+- Garbage collections
+- Reference counting
+
+## Compile-time logic
+
+- Annotation when calling function to be run as-far-as-possible at comptime
+
+```diff
+fn format(template: String, args: [String]) -> String {
+    template.replace("@", (match, i) => args[i])
+}
+
+fun add(x, y) x + y
+
+fun main() print(format!("@ ist @; @", ["1+1", 1+1, x]))
+# should expand to
+fun main() print("1+1 ist 2; " ~ x))
+```
+
+## Examples
+
+### Fizz-Buzz
+
+```diff
+for (n in 0..100) {
+    if (n % (3*5) == 0) print("FizzBuzz")
+    else if (n % 3 == 0) print("Fizz")
+    else if (n % 5 == 0) print("Buzz")
+    else print(n)
+}
+
+
+if (true) x = 1
+if (true) { x = 1 }
+```
+
+```
+f(x) = 10 + g(x)
+f x = 10 + g x
+
+main = {
+
+}
+```
