### Starting the REPL
* To start the REPL of an implementation in a specific step:
```
make "repl^IMPL^stepX"
# e.g
make "repl^ruby^step3"
make "repl^ps^step4"
```
* If you omit the step, then `stepA` is used:
```
make "repl^IMPL"
# e.g
make "repl^ruby"
make "repl^ps"
```
* To start the REPL of the self-hosted implementation, specify `mal` as the
REPL implementation and use the `MAL_IMPL` make variable to change the
underlying host language (default is JavaScript):
```
make MAL_IMPL=IMPL "repl^mal^stepX"
# e.g.
make "repl^mal^step2" # js is default
make MAL_IMPL=ruby "repl^mal^step2"
make MAL_IMPL=python "repl^mal"
```
