We have been stalled on ESLint 3.8.0 for some time. Current ESLint is 3.13.0. We have been unable to upgrade because of more aggressive reporting on some rules, including indentation. ESLint configuration options and bugfixes are now such that we can reasonably upgrade.

/**
|
|
* Creates a function that invokes the method at `object[key]` with `partials`
|
|
* prepended to the arguments it receives.
|
|
*
|
|
* This method differs from `_.bind` by allowing bound functions to reference
|
|
* methods that may be redefined or don't yet exist. See
|
|
* [Peter Michaux's article](http://peter.michaux.ca/articles/lazy-function-definition-pattern)
|
|
* for more details.
|
|
*
|
|
* The `_.bindKey.placeholder` value, which defaults to `_` in monolithic
|
|
* builds, may be used as a placeholder for partially applied arguments.
