Forced obfuscation of local function calls

Go back to reddit if you didn't already.

I laugh at those pathetic languages that can't get scoping right. Even C does it properly.

The problem now is that in Ruby you can (and usually do) leave off the parentheses enclosing the arguments on function call.
Outside of a context in which variables are immutable, that's really not what I'd call good style.

It's just common knowledge that Ruby is a misdesigned pile of shit.

foo = foo || 200
Do expert programmers really need to do this kind of shit with their ``properly'' designed languages?

I guess it's equivalent to
if(!foo)
 foo = 200;

Better known as the pseudo-object-oriented-C pseudo-singleton idiotm
Foo *foo;
...
if(!foo)
 foo = new_Foo(bar, baz); /* equivalent to foo ||= new_Foo(bar, baz);

Does anyone else find the lack of semicolons in Ruby disturbing?

Why would one want to emulate singleton instead of use a global variable?

Doesn't need to be initialized unless it's used.

That isn't an optimization. It is a useless branch each time you want to retrieve the object.

foo=foo||defvalue <==this is called sentinel value and its pretty common even outside of scripting languages, but using this carelessly is too common so foo must be initialized before the check to default value and changed later, like this:
foo=defvalue // foo is known to have default value before call
foo=bar()||foo // foo is now modified, if bar() returns null foo is preserved and any later code may call it without check

I enjoy this idiom in every language that supports it. Much better than having a built-in concept of default values.

The article wasn't abut this idiom though, but about how it interacts badly with optional function-call syntax.

Ruby is actually a very nice language, and these are just retarded quirks.

Using the variables names that are the same as functions is retarded programming. I would argue that the language shouldn't even allow this, or have an option.

I dislike ruby because every third line in an average ruby program is just "end". Lua has the same problem. At least use braces, for Hitler's sake.
