[ruby-core:101482] [Ruby master Bug#17398] SyntaxError in endless method

Issue #17398 has been updated by mame (Yusuke Endoh).


The body of an endless method must be an expression (called "arg" in the syntax rules of parse.y). `puts("bar")` is an expression, but `puts "bar"` is a statement (called "command" in the syntax rules).

I think it could be a bit confusing, but I have no idea whether we can/should allow a statement as a body of an endless method.

Bug #17398: SyntaxError in endless method

* Author: zverok (Victor Shepelev)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
----------------------------------------
This works:
```ruby
def foo() = puts("bar")
```

This does not:
```ruby
def foo() = puts "bar"
#                ^ syntax error, unexpected string literal, expecting `do' or '{' or '('
```

Is this intentional or accidental? Not sure how it is reasoned.
