Check types

How to check a type of a variable?

type(x)

type(x)

type(x)

type(x)

raises an error

isinstance(1, Int)

isinstance(1, Int)

isinstance(1, Int)

isinstance(1, Int)

also raises an error

I was only able to print the types using:

struct print_type:
    fn __init__(inout self, type:Int):
        print("Int")
    fn __init__(inout self, type:Float64):
        print("Float64")
    # ...

struct print_type:
    fn __init__(inout self, type:Int):
        print("Int")
    fn __init__(inout self, type:Float64):
        print("Float64")
    # ...

struct print_type:
    fn __init__(inout self, type:Int):
        print("Int")
    fn __init__(inout self, type:Float64):
        print("Float64")
    # ...

struct print_type:
    fn __init__(inout self, type:Int):
        print("Int")
    fn __init__(inout self, type:Float64):
        print("Float64")
    # ...

However it seems to be not possible to return the type instead of just printing it

struct print_type:
    fn __init__(inout self, type:Int) -> AnyType:
        print("Int")
        return Int. # Error

struct print_type:
    fn __init__(inout self, type:Int) -> AnyType:
        print("Int")
        return Int. # Error

struct print_type:
    fn __init__(inout self, type:Int) -> AnyType:
        print("Int")
        return Int. # Error

struct print_type:
    fn __init__(inout self, type:Int) -> AnyType:
        print("Int")
        return Int. # Error
