----------------------------------------
Bug #13012: irb fails to define a method with a reserved-word-ish keyword argument 
https://bugs.ruby-lang.org/issues/13012#change-63795

* Author: matsuda (Akira Matsuda)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.0dev (2016-12-07 trunk 57012) [x86_64-darwin14]
* Backport: 2.2: DONE, 2.3: REQUIRED, 2.4: DONTNEED
----------------------------------------
For example

```
def a(if:) end
```

is a valid ruby code but this doesn't work on irb.

This seems to be happening for all keywords that are listed in `RubyLex::ENINDENT_CLAUSE`
