Extend :isset element handling in view to support multiple vars

[iamdadmin]

Description

Would there be any interest in a PR to refactor tempest/view :isset element handling so it can handle complex expressions? The :isset element literally wraps whatever it's given in isset() expecting a true or false

<x-template :isset="$var1" < currently works

<x-template :isset="$var1 || $var2" < currently does not

<x-template :if="isset($var1) || isset($var2)" < what you have to do right now for the equivalent

I therefore propose to extend this so that when multiple $vars are detected, it will wrap each instance of $var and as long as it returns true or false, according to developer needs, it will issue true or false.

It should also support multiple cases, as long as the expression can be written to correctly return a true or false using isset() statements only.

For more complex cases, then :if should still be used.

Benefits

Developer experience and efficiency in code.
