However, the crucial difference is that type aliases are assignment-compatible with their underlying type (and with other type aliases with the same underlying type), while inline classes are not.

I CAN’T pass BigDecimal to a function that takes MoneyIC.
Bottom-line: inline classes provide for stronger typing of wrapped class.
