Lexical autocomplete #1063
Description
Describe your feature request
According to comments in #901, autocomplete has no native implementation and relies solely on LSP. A consequence of this is that when the user has no LSP installed, or one doesn't exist for the file type you are editing, there is no autocomplete at all.
It would be nice if there was a built-in autocomplete that is based purely on the tokens in the current document, without any language awareness.
