Yep! I've been learning PHP after learning Swift, and I leave off semicolons all over the place!

Hi Noah and Greg,

Things only get uglier when you have to deal with Ruby what uses..

(drum roll please)

double colons

: :

Some related (explanatory) quotes..

The :: is a unary operator that allows: constants, instance methods and class methods defined within a class or module, to be accessed from anywhere outside the class or module.

Per this page:

http://marcricblog.blogspot.com/2007/11/ruby-double-colon.html

When a receiver is explicitly specified in a method invocation, it may be separated from the method name using either a period “.” or two colons “::”. The only difference between these two forms occurs if the method name starts with an uppercase letter. In this case, Ruby will assume that a receiver::Thing method call is actually an attempt to access a constant called Thing in the receiver unless the method invocation has a parameter list between parentheses.

per this page:

It's called a scope resolution operator. Basically a fancy way of referencing a class within a namespace.

per this StackOverFlow thread:

Long story short:

That's twice as many opportunities to drop a colon!
