## Todo (pre-release, in this order):
|
||||
- Write "how it works"
|
||||
- PyPi package
|

|
||||
## Todo:
|
||||
- Prevent macro-chaining recursion
|
||||
- Cleanup warnings
|
||||
- Truncate long expressions in warnings
|
||||
- History indexing
|
||||
- Show history command
|

- $\alpha$-equivalence check
|
||||
- α-equivalence check
|
