The current definition:

An ordinary identifier is composed of a leading alphabetic character which may be followed by one or more alphanumeric characters. It may also contain isolated, embedded apostrophes ' and/or hyphens -, provided that the next character is each time alphabetic.

This means that '2-5-7' is NOT an identifier but the numerical value -10.

Thanks for the link and the excerpt. Just out of curiosity, did the capitalized "NOT" was there because my above message was interpreted as a guess that `2-5-7` could serve as an identifier in Raku? That was not my belief nor what I tried to expose, to be clear on that point.

Thank you again for your reply.

Yeah, it was. Sorry, misread :-)

No worry, we all do that here and there. ;)
