Errors opening vim syntax/fennel.vim, line 253 Range too large in character class

[mikemee]

Any idea why these errors might be occurring on a pretty minimal installation of vim (when opening a .fnl file)?

Thanks in advance … perhaps something to do with vim 9.0 (seemingly recently adopted as a default by Apple)?

Thanks for reporting this - looks like something needs to be done for vim9 compat - I'll make sure it's fixed soon and then start testing against vim9 moving forward when nontrivial updpates are made.

Thanks. Not at all urgent. I didn't choose vim9, but some Apple update or other added it. This isn't the only thing that's a bit weird with it. Fortunately I have few plugins or non-default settings.
