In FictoScript, the `freeze` function applied to a list will:
Answer: Make the list immutable so no elements can be added, removed, or changed
`freeze` locks a data structure, making any subsequent mutation attempts raise a FrozenError.
Which FictoScript feature allows a single function name to behave differently based on argument types?
Answer: Overloading via `fn/type` dispatch
FictoScript supports type-based dispatch by defining multiple `fn/type` signatures under the same function name.
A FictoScript `lazy val` is evaluated:
Answer: Only the first time it is accessed, then cached
`lazy val` defers computation until first use, then memoizes the result so subsequent accesses are instant.
In FictoScript, what does `filter(fn(x) => x mod 2 == 0, [1, 2, 3, 4, 5, 6])` return?
Answer: [2, 4, 6]
`filter` keeps only elements where the predicate returns true; here, even numbers pass the `mod 2 == 0` check.
FictoScript's `trait` keyword is most similar to which concept in other languages?
Answer: An interface or mixin that defines behavior a type must implement
A `trait` defines a set of method signatures (and optionally default implementations) that types can adopt.
What is the purpose of FictoScript's `seal` keyword applied to a module?
Answer: Prevents external modules from extending or overriding the module's definitions
A `seal`ed module cannot have its definitions monkey-patched or extended by other modules, ensuring stability.
In FictoScript, if a `loop` body contains `break(42)`, what happens?
Answer: The loop exits and the entire loop expression evaluates to 42
FictoScript loops are expressions; `break(value)` exits the loop and returns that value as the loop's result.
