We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Run REPL using `python -m hy`
Figuring out how to get a REPL is not trivial. What do you think about making `python -m hy` do it?

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
--- BEGIN FILES ---
Path: `hy/__main__.py`
Content:
```
1 import hy  # NOQA
2 import sys
3 
4 # This just mocks the normalish behavior of the Python interp. Helpful to aid
5 # with shimming existing apps that don't really "work" with Hy.
6 #
7 # You could say this script helps Hyjack a file.
8 #

11 if len(sys.argv) > 1:
12     sys.argv.pop(0)
13     hy.importer._import_from_path('__main__', sys.argv[0])
14     sys.exit(0)  # right?
