Hi, thanks for the great project.

I just discovered typer and interactive shells a few weeks ago so please excuse me if this is something obvious.

I currently converted my existing cli to a interactive shell so that data structures that needed to be pre-loaded in the background can be utilized better in a interactive shell session.

however my cli program relied on commands/binaries in the parent shell to work such as gcloud kubectl, etc is there anyway that make_typer_shell will allow the creation of the current user shell configs as a new shell with the interactive components?

hey @FergusFettes feel free to take a look at this whenever you have time, but i've tried to modify your shell() to 


def shell(ctx: Context):
    """Drop into an ipython shell"""
    import IPython
    env = os.environ.copy()
    IPython.embed(user_ns=env)

and other similar tests to inherit the parent shell behaviors but still had no avail.

@nia-potato hmm, im not sure if this will work-- you cant use bash binaries directly in python shells in general i think.

but I can still use the bash elements in the parent environment like so:

p/txt/typer-shell> export TEST='asdf'
p/txt/typer-shell> poetry run python demo.py
