Component name "Block" throws error during compilation.

[milkbump]

Describe the bug
The component name "Block" seems to throwing the Svelte compiler off.

<script>
    import Block from "./Block.svelte"
	
</script>

<Block>my block</Block>

results in the error:

Identifier 'block' has already been declared (Note that you need plugins to import files that are not JavaScript)

But simply changing the component name import Blocky from "./Block.svelte" //path is the same works. Also, using the Block component more than once get's rid of the error.

Weird. I thought this would have been fixed in the latest 3.13.0 alphas but this does not seem to be the case. Thanks for the report!

This only affects dev mode. It looks like the block variable that's passed to dispatch_dev("SvelteRegisterBlock", ...) isn't properly deconflicted with existing variables.

This is happening for me too after extracting block out to new a component.

import Block form './Block.svelte'
doesn't work
refactoring to
import BuildingBlock from './Block.svelte'
does work

Wow, @kwangure, you had the same problem at the same time as me. Incredible.

Maybe it's a problem with slots
