An API to register an overdubbing REPL?

[mbauman]

In testing out a change, we found it quite helpful to use ReplMaker.jl to create a custom REPL prompt that applied a cassette transform. It's super easy!

using Cassette, ReplMaker

Cassette.@context Ctx
# Do overdubbing...
function parse_to_expr(s)
    p = Meta.parse(s)
    isa(p, Expr) && p.head in (:using, :import) && return p
    quote $Cassette.@overdub($(Ctx()), $p) end
end
initrepl(parse_to_expr,
                prompt_text="Ctx> ",
                prompt_color = :blue,
                start_key=')',
                mode_name="Ctx_mode")

Is this something worth upstreaming here? Maybe as a flag to @context to create a REPL?

Huh, that is fun! Should definitely go into https://github.com/jrevels/DemoTapes.jl
