Hooks failure on functional component as root

simple code like

import { h, render } from 'preact'
import { useState } from 'preact/hooks'

function Root(props) {
 const [ c, setC ] = useState(0) 
 return h('h1', { onClick:()=>setC(c+1) }, `counter is ${c}`)
) 

render(Root(), document.body)

fails with TypeError: Cannot read property '__H' of undefined due to undefined currentComponent within hooks

notice that currentComponent is set on pre-render phase, but in case of Root being functional hook must be initialized before any render.

Just noticed that many issues were similar to mine, but in other situations. Users had troubles with that and minified CDN versions of preact are little bit mysterious on that. Maybe some doc mentions on that would be also useful. Ok, thanks for your lightning fast and valuable support…and for great preact.

No it can’t, do you have a use case where you would want to use a hook outside of render?

Do note that preact/debug warns you for these.
