----------------------------------------
Bug #20597: `eval('break if false')` should raise SyntaxError but retuns nil
https://bugs.ruby-lang.org/issues/20597
* Author: tompng (tomoya ishida)
* Status: Open
* ruby -v: ruby 3.4.0dev (2024-06-27T13:47:22Z master c6a0d03649) [x86_64-linux]
* Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN
----------------------------------------
These are all SyntaxError (Invalid break, compile error (SyntaxError))
~~~ruby
ruby -ce "break if false"
ruby -ce "break if (false)"
ruby -ce "break if nil"
ruby -ce "break if (nil)"
ruby -ce "break if 0>1"
~~~
But when it is passed to `eval`, some of them does not raise SyntaxError but return nil.
~~~ruby
eval('break if false') #=> nil
eval('break if (false)') #=> nil
eval('break if nil') #=> nil
eval('break if (nil)') #=> Can't escape from eval with break (SyntaxError)
eval('break if 0>1') #=> Can't escape from eval with break (SyntaxError)
~~~
Same behavior with `next` `redo` and `yield`
