and gets even worse if you bring variables into the game.

a = 5

b = 3

everybody from nearly every programming language would expect that after

c = a-b

you will find c to be 2 not nil (or throwing an exception or whatever)

I never pack my code like that without whitespace, as doing so is only readable when you have single-letter variables, which is not very common.

I agree with the OP. CamelCase and underscores are both scourges.

[haukur]

I've always found code without spaces around these symbols to be very undreadable.

[pilot_pirx]

Yes, but in this case it's not about readability, but about extremely significant whitespace. Forgetting a space and your code has a totally different meaning.

[xyzzyb]

Whitespace is already extremely significant in programming. "foo[1]" vs "foo [1]" for example.

[pilot_pirx]

Depends on language, in Ruby those statements would be identical. But anyway, that's no reason to make things even worse.

[mbrubeck]

In Ruby those statements are the same when foo is bound to an array, but they are different when foo is bound to a function...

And I have found the opposite. Horses for courses.
