So the instructions for multi-line comments say the =end needs to be on its own line, and the editor coloring seems to agree. If you have a line starting with =end but with something after it like “=end hello”, then the text color remains the same as a comment until it sees =end by itself on a line.

However, the interpreter seems to think that any line starting with =end is the last line of the comment, and anything directly after =end on the same line remains a comment but lines after that are not.

Here is a screenshot of my tests.

If it’s not in the spec, we should not expect code to run how we want. Ruby has a very well defined and strict interpreter. If the spec says =end gets its own line, then respect that.

This likely traces back to heredoc syntax prescibed in other languages from which Ruby has evolved.
