Possible bug during object init (or perhaps scala just throws away code that produces only side effects)
object Foo {
val bar = { println("bar"); 42 }
}
object Foo2 {
val bar = { println("bar") }
}
// scala> Foo.bar
// bar

SML code that leads to type inference fail.
fun all_answers func [] = SOME []
fun all_answers func xs = let
fun loop [] = []
| loop (h::tail) = case (func h) of
SOME x => x :: loop tail
| NONE => loop tail
in case loop xs of
[] => NONE
| lst => SOME lst
end

Git hook written in python. I had a habit of leaving 'if' statement without following space which really annoyed my collegues. So I've written git hook which checks if there is some nasty ifs, and if so, it will reject commit until I fix an issues.

SML sandbox. I place here most of the stuff, I've done during coursera course. If you don't like **SPOILERS**, please, move along, don't look inside.

An example, I've written to show some **very** basic swing constructs to my classmate

import java.awt.*;
import java.awt.event.ActionEvent;
public class Foo {
static final JFrame MainWindow = new JFrame();
static final JPanel content = new JPanel(new BorderLayout());
static final JLabel resultFromDialog = new JLabel("SomeText");

Remove the words where last character is a capital letter from a given sentence and then reverse the characters of each word
"FooO bar baZ bow".split(" ").filter(word => word.last >= 'a').map(_.reverse)
