Symbols

A symbol means a name given by a programmer to anything in the program (dependently on the language it can be variable, function, class, structure, union, trait, module, interface etc.). In Plezuro everything is a variable so each symbol represents a variable.

The rules of the variable naming:

1. The first character must be an ASCII letter or the underscore (‘_’).
2. The next characters must be an ASCII letter, the underscore or a digit.

Declaration

Eeach symbol must be declared at the first use in the source file. The declaration contains the dollar sign $ and the name of the symbol.

Class fields

Class field (or module field) contains the name of the module, the double colon :: and the name of the field (the same rules like for the symbol).

Object fields

Object field (or module field) contains the at character @ and the name of the field (the same rules like for the symbol).
