add a unit test where there is only # month specified, but nothing else.
and another one with only # year.
and then one more for year + month.
and one for only day, week, ... all the units.

also add a unit test where the string is just "int", and one for empty string.

do we need to test all the combinations of units?

Looks good other than documentation / test cases. I'm assuming code gen is left for the next task for cast? |

Ah sorry forgot the code gen part. Will add it and the tests, documentation improvement. |

probably not - but we should definitely test each unit at least once.

remove i and use null directly.
"i" is a bad name since it is usually used for iterating over an array.
