 * Forth-style data stack for parameters/values
 * Linking with C functions (see `support.c`)
+* Recursion: `$self` gets pointer to current function
 
 Missing features:
 
+* Captured variables: Functions/lambdas are *not dynamic* and do not capture the state of previously declared variables
 * Quote operator: `quote`/`'`
-* Lists and atoms or any dynamic allocations
+* Built-in dynamic allocations (implement them via platform-specific `support.c`)
