Scalars are value types. They contain their payload directly and don't need boxing.

  • Characters are enclosed in double quotes \" and can make use of the escape sequences \n, \t, \" or \ to produce a newline, tab, double quote or backslash character, respectively. If more than one unescaped character is enclosed in quotes, the noun is a list of characters (see below), also known as a string.
  • Symbols start with a backtick ` and are followed by an optional name. Names must start with a dot or a letter, and may contain letters, digits or a dot. Symbols are mainly useful as handles for variable names or keys in dictionaries.

O has following scalars:
