🐉 Membership & Type Operators

in

Checks if a value is contained within a string, list, or map:

fruits = ["apple", "banana"]
when "apple" in fruits
    say "Found it!"
end

# Check substring
when "hello" in "hello world"
    say "Matches substring!"
end

typeof

say typeof 42          # "int"
say typeof "Hello"     # "str"
say typeof [1, 2, 3]   # "list"
