Scala Symbols

https://docs.scala-lang.org/tutorials/FAQ/finding-symbols.html

We can divide the operators in Scala, for the purpose of teaching, into four categories:

• Keywords/reserved symbols

• Normal methods or values

• Methods provided by implicit conversion

• Syntactic sugars/composition

And let’s see some arbitrary examples:

The exact meaning of most of these methods depends on the class they are defined on. For example, <= on Int means “less than or equal to”, but it might mean something else in another class. :: in an expression is probably the method of the class List but it can also refer to the object of the same name (and in a pattern it definitely does).

So, let’s discuss these categories.
