# Primitive types
typeof(42)
# → 'int'

typeof(3.14)
# → 'float'

typeof(True)

typeof(None)
# → 'nil'

typeof("Catnip")

typeof(list(1, 2, 3))
# → 'list'

typeof(tuple(1, 2))

# Functions
typeof(() => { 1 })
# → 'function'

# Structs return their type name
struct Point { x; y }
typeof(Point(1, 2))
# → 'Point'

# BigInts are still 'int'
typeof(2 ** 100)
# → 'int'

# Useful in conditions
if typeof(42) == 'int' { "yes" } else { "no" }
# → 'yes'
