true == true and false == false

true == true or false == false

true and true

true or true

In all cases it returns 0 but 1 (or true) is expected, it seems the evaluation is broken when using the boolean operators true and false

var x - 1

As expected I get an error

Invalid Syntax: Expected '='

and then the program crashes.

I need to investigate this, seems weird.
It probably comes from the Parser::binary_operation and its arguments.
For now, it takes two vectors for the token types and values to operate on.

But during the comparison, we need to compare either a tuple or a single value.
I need to put this in place.

Any suggestions are welcome.

var mel = PI / 4
manuel = PI * 10
var manuel = mel > 10

The last line raises an error :

terminate called after throwing an instance of 'std::bad_variant_access'
  what():  std::get: wrong index for variant
Abandon (core dumped)

When entering an illegal character, the lexer display the error and crashed.
It's probably due to the parser which can't proceed properly.
