v0.1.12

• BinaryOperatorRegistry no longer ends up in an invalid state when an InvalidArgumentException thrown by BinaryOperatorRegistry::register() is handled
• Numbers with multiple decimal points (such as 3..2, 3.2.1, etc.) are no longer parsed as numeric literals
• Function call token's "end pos" is now at closing parenthesis of its argument list
  • Parse exceptions arising from function calls are more comprehensible
