TODO

Utilities

• Debugging system for the language itself.
• REPL - (it would be very nice to allow multi-line commands).

Language-wise

• Run programs inside a scheduler (WIP).
• Error handling! Capture exceptions in D and reflect it as ExitCode.Failure in Til.
• User-defined search path for dynamic libraries.

Error handling

Initial conception:

proc remove (filename) {
    on_error (e) {
        # If not found, it's already removed, so it's okay:
        if (<$e code> == $file_not_found) { return }
        
        # If it's another error, pop it to the caller to
        # decide what to do:
        throw $e
    }

    shell.rm $filename
}

If an error occurs inside the current scope, on_error is "called" and it's scope will be considered instead of the previous one (so that the programmer can choose to return a "neutral" ou "default" value, for example, or throw the error up in the call stack).

Commands

• exit $exit_code - quits the program with a numerical value (like "exit" from unix shells).
• list a b c → (a b c).
• type → :Atom/:String/:List/:ExecList/:SubProgram (so we can have some type of "pattern matching" using case.
