Change "parsing error" to "reserved word not allowed" when naming a function "delete"

[rbecheras]

When we name a function delete, standard find a parsing error.

Here an example in atom editor with the plugin linter-js-standard:

I would suggest using a more semantic error name/type/description. Something like

Function naming error: 'delete' is a native reserved word

Thanks for the suggestion. I wish that we could show a friendlier error, but in this case the usage of the token delete is literally crashing the JS parser, since it's not expecting a reserved word to be used in that location.

I don't think there's an easy solution that standard can apply here, since this error originates in ESLint. If you feel strongly that this should be improved, consider opening an issue on the ESLint issue tracker. https://github.com/eslint/eslint
