Why are C# 3.0 object initializer constructor parentheses optional?
...oblems with unexpected interactions with features in the future.
All for what? A tiny customer benefit that adds no new representational power to the language, but does add crazy corner cases just waiting to yell "gotcha" at some poor unsuspecting soul who runs into it. Features like that get cut ...
Why is Git better than Subversion?
... better.
Subversion has Problems, but so does Git, Mercurial, CVS, TFS or whatever.

a, b = 0, 1
while True:
a, b = b, a + b
yield a
This never terminates but will generate the Fibonacci numbers. You can get as ma...
