this was from eslint/eslint#15017

acorn can parse var char = 0; with no errors (ecmaVersion: 3). but char is a ES3 reserved word:

any reasons the option allowReserved defaults to true? IMHO, it makes sense defaults to false in non-loose mode.

Most browsers in the ES3 era allowed reserved words to be used in scripts, hence this default. It is not going to change for backwards-compatibility reasons.
