Functions

[mrodz]

• Specify arguments for function calls.
  • Should it pass the current operating stack as arguments? yes! ✅
• make_function instruction to create a function "pointer"
• call should be able to call a function "pointer"
• New primitive: Function Pointer
  • Contains the location of the function.
  • Can contain an Arc of variables to freeze, perhaps to facilitate callbacks. This is tentative.

The line to distinguish this feature from #12 is very blurry. Stay tuned for updates as I decide what should go into which branch.

Note: I am using "pointer" very loosely here, as it is not an integer that points to a location in memory. It contains a String that tells the interpreter how to find a function.
