"Octal literals are not allowed in strict mode." is not a synax error

[tom--]

 SyntaxError: Octal literals are not allowed in strict mode 

The error message is not technically correct. Octal, hex, decimal etc. are differences in morphology, not syntax. So it is a grammar error and, more specifically, it is a morphology error but it is not a syntax error.

The error comes from V8 not from node. Sadly, there is no MorphologyError built into JavaScript.

@tom-- Node.js uses v8 JavaScript engine and the error is thrown when v8 parses your source code. You might want take this up with the v8 project.
