[ruby-core:81006] [Ruby trunk Bug#13536][Open] Ripper fails to tokenize nested squiggly heredoc

Issue #13536 has been updated by shyouhei (Shyouhei Urabe).

Status changed from Closed to Open

Thank you, the exception disappeared.

But it seems incomplete.  Look at this slightly different example:

```
require 'ripper'

str = \
<<~'end'
<<~"do"
#{
<<~"begin"
 this must be a valid ruby
begin
}
do
end
puts eval(str)
str == Ripper.tokenize(str).join
```

The last line does not raise exception, but evaluates false.

```ruby
require 'ripper'

str = \
<<~'end'

this must be a valid ruby
begin
}
do
end
puts eval(str)

```

This program fails at the last line.
