Failure to tokenize multi-line comments

[silverhairs]

Out to reproduce:

1. Start the REPL
2. Input a multi-lines comment such as /* example comment */
3. Press enter

> /* this is a multi-lines comment*/        
&{Type:ASTERISK Literal:<nil> Lexeme:* Line:1}
&{Type:SLASH Literal:<nil> Lexeme:/ Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
> /* this is a multi-lines comment */
&{Type:ASTERISK Literal:<nil> Lexeme:* Line:1}
&{Type:SLASH Literal:<nil> Lexeme:/ Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
&{Type:EOF Literal:<nil> Lexeme: Line:1}
> 

As seen in the output above, the lexer completely ignores all the lexemes that come before the closing */.
