LeifW / gist:1015583

Created June 8, 2011 22:21

Comparison of languages.

	Earlier I said Haskell/Scala/Python/Ruby/CoffeeScript are all pretty much the same.
	By that I meant you can write much the same code in all of them, just the syntax might look a bit more weird or arbitrary in some cases.
	Of course there are fundamental differences in the type of things you write in static versus dynamic languages, just as there are fundamental differences between what you write in a lazy vs eager language.

	Print the numbers one through ten:

	Python:
	for i in range(1,11):
	print(i)
