    Copy code
    fun add(x: Int, y: Int): Int = Python<Int>(::add, {"""
        print "hello from python!"
        return x + y
"""})

    If I recall Python is pretty loose about typing as well, I've seen/had problems when interacting with a loosely typed language from a strictly typed language before.

    @dalexander: Its not that, I need to introspect the kotlin add function

    define a kotlin function and have it execute in a different language

    @jkbbwr: you can make it a little better by using infix functions: 
    fun add(x: Int, y: Int): Int = ::add python {“”” … “”” }

    But how do I find add in the first place

    no way right now

    but I think it now gives an idea about what function delegation could mean

    fun fn() by python { … }
    would mean 
    fun fn() = (python {…}).invokeValue(this, KFunction)
    like 
    getValue
    for property. And then you have all metadata implicitly

    if (s1 == null ^ s2 == null) {
    genius! The best way to write 
    (a == null && b != null) || (a != null && b == null)
    🙂

    @miha-x64 can you link to anything defining this behavior? Quick check of the docs and I can’t find anything

    xor, exclusive OR

    oh it’s a java operator. I actually didn’t know there was an xor operator

    guess I’ve just never needed it, good to know!

    hard for me to think about xor without ⊕ 🙂

    Now I understand why JetBrains developed Kotlin 🙂 
    NotNullLazyValue
    , 
    AtomicNotNullLazyValue
    , 
    StringUtil
    , 
    FileUtil
    , 
    ExecUtil
    , and so on simple smile

    Totally hyped about Steve calling kotlin "one of the best new languages to emerge in a long, long time" http://steve-yegge.blogspot.com/2016/11/the-monkey-and-apple.html
