This used to improve performance, but as of ESLint 5 and v2 of this plugin, it seems to just consume a bunch of memory and slightly increase lint times.
Not recommended for use at this time!
This parser is just a memoizing wrapper around some actual parser.
To configure, just add your actual parser to the parserOptions, like so:
parser: eslint-plugin-import/memo-parser # parser: babel-eslint parserOptions: parser: babel-eslint sourceType: module ecmaVersion: 6
