Subject: [ruby-core:107911] [Ruby master Bug#18635] Enumerable#inject without block/symbol will return values or raise LocalJumpError

Issue #18635 has been reported by bjfish (Brandon Fish).

----------------------------------------
Bug #18635: Enumerable#inject without block/symbol will return values or raise LocalJumpError
https://bugs.ruby-lang.org/issues/18635

* Author: bjfish (Brandon Fish)
* Status: Open
* Priority: Normal
* ruby -v: 3.0.3
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
The following shows inconsistent behavior when no block/symbol are provided to inject.

``` ruby
irb(main):002:0> {}.inject
=> nil
irb(main):003:0> {one: 1}.inject
=> [:one, 1]
irb(main):004:0> {one: 1, two: 2}.inject
(irb):4:in `each': no block given (LocalJumpError)
irb(main):005:0> [].inject
=> nil
irb(main):006:0> [1].inject
=> 1
irb(main):007:0> [1, 2].inject
(irb):7:in `each': no block given (LocalJumpError)
```

I would expect the results to be consistent by always raising a LocalJumpError or raising an ArgumentError when no block and symbol are given.
