Hey all y'all,
Here's another nice bicycle shed discussion. During the recent
discussion about globals being harmful, Walter told me something that
made me think. I said, hey, there are things that are global - look at
stdout. He said, well, that's a bad thing. He then argued that it
would be better and cleaner to write:
stdout.writeln("Hello, world");
instead of the current:
writeln("Hello, world");
On one hand, I agree with Walter. On the other, I want to avoid the
phenomenon of the all-too-long "Hello, world" example.
What do you think?
There must be something I'm missing here. Either writeln is using a
global "stdout" which you can't see in it's interface, or you are using
that global "stdout" yourself and invoking writeln on it. There's still
a global around. Nothing solved.
The difference is that in the current call the use of the global is
implicit.
