Description
## Expected behavior
in evil mode w motion should work on clojure symbols for example: this-symbol?!
## Actual behavior
currently the motion will only include 'this' - i.e up to to the hyphen.
## Steps to reproduce the problem
std doom-emacs with clojure mode
## Environment & Version information
### clojure-mode version
```
clojure-mode (version 5.16.0)
```
### Emacs version
GNU emascs 27.1
### Operating system
Linux 5.15.0-67-generic #74-Ubuntu SMP Wed Feb 22 14:14:39 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
# Suggested change
I am not too familiar with emacs lisp or the clojure mode so this is just a suggestion - it has worked for me in my local configs.
add the following extensions to the word syntax definitions in the clojure-mode-syntax-table (there may be a more compact way of expressing that but I am not familiar with required syntax).
you may or may not want to include the # character. I found it useful and it is accepted in symbols
I am not certain how/if to this should be changed where a character is not allowed as the first char of a word....
I note also that motions like yW are a problem because they pick up brackets when at the end of an expression. So I also included # / : and . because these are useful. There may be a better way to include these...
