Does it make sense to anyone else that chomp tests and carps about receiving a read-only parameter, before it tests whether it would require modification?

Yes. It is well documented that chomp only works if you give an lvalue to work with.

I don't want to sound cruel but you want to modify core functionality for a very specific edge case. Good luck getting it implemented.

It's easier to go with what works. Use a temporary variable if you think that someone will pass you a constant.

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or or How to display code and escape characters are good places to start.
