/*
    - Rust style data types
    - New inbuilt keywords instead of functions:
        - alloc [pointer variable name] [n];
            Stores a pointer to n bytes in memory
        - asm   [string];
            Passes the given string directly to the backend, treated as assembly code.
        - free  [pointer variable name];
            Frees an alloc'd pointer
        - input [variable name];
            Initialises the variable by immediately asking the user to input its value.
        - print [string]
        - print [variable name];
            Outputs the value of the variable
        Different implementations are picked at compile time depending on the data type. i.e. string or integer and the target (jupiter/linux/freertos)
        If a feature is not possible on the selected target such as embedded hardware, error out.
