Programming Language Evaluation

A list of simple tasks to perform when learning or evaluating a new language. Each of these should be able to be completed in a few hours, and will help to get the feel of the language and its standard libraries. A well-rounded set of evaluation tasks will help ensure all parts of the language are exercised. You might also write some tests to demonstrate implementation correctness.

Basics

Hello world
Read lines from a text file and output them in sorted order
Read numbers from a text file and output the mean and standard deviation
Given an amount of money and a list of coin denominations provided on the command line, output all the possible ways to make change

	I went to see the Hobbit in HFR 3D IMAX OMGWTF today. Movie verdict: 3 hours is too long to sit in
	the theater. It's not necessarily too long for home viewing where you can get up and move around,
	or pause the movie and take a break, but it's too long for the theater. That said, it's a well-made
	film and PJ keeps the story moving along, so you'll be entertained, even if your eyes and butt are
	sore as hell by the end of it!

	Stereo 3D verdict: yep, I still hate it. Kill it with fire. Especially the parts where they flick
	stuff at your face - it's such a stupid, cheap trick.

	HFR verdict: really interesting experience. The picture is great - very clear and smooth and BRIGHT
