Not a single form field has a label. These designs are not usable and the patterns presented should be discouraged.

I suggest adding a validation check like Nu Validator, aXe, lighthouse, etc. to show all the places this markup is invalid.

When you throw an exception (throw new \Exception('Some error...');) in CLI mode the script silently dies without no output to the console. It is only logged in PHP's error log.

That should not be default behaviour I would say.

Btw, this is on Windows. If I run it in my Linux environment it should just fine.

Reproduction:

=> (sp/render "{{ props.docs|default:@props.notes }}"
              {:props {}})
"@props.notes"

In the templates I’m writing, I had expected the filter to return either nil or a blank string.

@yogthos I’m not sure if we should consider this a bug or a feature request, but either way, what do you think?
