Disable format in an error message

[nanoqsh]

When I display an Error I got a message like this:

  --> 18:17
   |
18 |                 ]␊
   |                 ^---
   |
   = expected array, boolean, null, number, object, or string

Can I get only text message like this expected array, boolean, null, number, object, or string without any formatting?

Yes! Try displaying Error's public variant field, instead.

[nanoqsh]

Thanks!
