Closes partially #80 ### Summary of Changes * Show an error if literal types have no literals * Show an error if lists or maps are used in a literal types * Mark literal types as experimental (show a warning when they are used) * Compute type of manifest literal types * Evaluate literals to a literal type instead of the corresponding class. For example, the literal `1` now gets the type `literal<1>` instead of `Int`). --------- Co-authored-by: megalinter-bot <[email protected]>

For numbers, for examples, it should be possible to express that only a finite set of values is legal. This could be expressed by enum but that's quite cumbersome and you can no longer operate on enums like you could on, say, numbers.
Desired solution
Literal types:
literal<"a", 1, true>Open tasks
literal<"a", "b">, we can access any members ofString. On something of typeliteral<"a", 1>, we can access any members ofAny. On something of typeliteral<"a", 1, null>, we can still access any member ofAny(scoping), but must use a safe access (validation).TypeComputer.computeClassTypeForLiteralTypeThe text was updated successfully, but these errors were encountered:
