Represents a single symbol of the grammar. This is an immutable class.
For a symbol name to be valid it must NOT contain control or separator characters, must not be empty and must meet these conditions:

Represents a single symbol of the grammar. This is an immutable class.
For a symbol name to be valid it must NOT contain control or separator characters, must not be empty and must meet these conditions:

| Mercury.Syntax.Symbol.Symbol | ( | string | name | ) |
| Mercury.Syntax.Symbol.Symbol | ( | string | name, |

Creates a new symbol with desired type. If the constructor does not throw any exception, the symbol is guaranteed to be valid.
| name | Symbol name |
| type | Desired symbol type |
| System.ArgumentNullException | name |
| Mercury.Exceptions.InvalidSymbolException | When the symbol is not valid. |
| Mercury.Syntax.Symbol.Symbol | ( | Token | token | ) |
Creates a new terminal symbol from a token. If the constructor does not throw any exception, the symbol is guaranteed to be valid.
| token | Input token |
| System.ArgumentNullException | token |
| Mercury.Exceptions.InvalidSymbolException | When the symbol is not valid. |

Infers the type of symbol according to conditions described in the constructor documentation.
If input meets terminal a) condition (= terminal or epsilon), this method returns SymbolType.Terminal | SymbolType.Epsilon.
