-# class-based-helpers-disambiguation
+# Helpers disambiguation in Embroider
 
-This README outlines the details of collaborating on this Ember application.
-A short introduction of this app could easily go here.
+A minimal repro for the issue of helpers breaking when called in the unambiguous way:
 
-## Prerequisites
+`{{(translate)}}`
 
-You will need the following things properly installed on your computer.
+It turns out that no matter what kind of helper you have (class-based, functional or plain-function), they all break when called as above.
 
-- [Git](https://git-scm.com/)
-- [Node.js](https://nodejs.org/)
-- [pnpm](https://pnpm.io/)
-- [Ember CLI](https://cli.emberjs.com/release/)
-- [Google Chrome](https://google.com/chrome/)
+**What matters is that `staticHelpers` be set to `false` in the config.**
 
-## Installation
+If it is, it breaks with the following:
 
-- `git clone <repository-url>` this repository
-- `cd class-based-helpers-disambiguation`
-- `pnpm install`
+```
+Uncaught TypeError: func is not a function
