Enable REPL for a Generic interpreter

[mathjiajia]

I add something like

interpreter_options = {
    Generic = {
        Swift_original = {
		supported_filetypes = { "swift" },
		extension = ".swift",
                interpreter = "swift",
		boilerplate_pre = "import Foundation",
	},
    },
}

how to enable REPL support for it?

Enable REPL for a Generic interpreter

Unfortunately it's not really possible. While the (non-REPL) "file -> compiler -> binary -> output" workflow is relatively standard over number of languages, it's not as easy to generalize a "file | interpreter | output": many intepreters have quirks and there is some language-specific code too.

A purpose-built interpreter is better suited to REPL functionality
