Add string_to_quoted in Code.Fragment

The idea is that the code will be incomplete and we will try to fix it.

@lukaszsamson, is the cursor position relevant when trying to fix it? Or do we rely exclusively on indentation?

@lukaszsamson @scohen @scottming can you please provide many examples of what you expect here? Like:

def foo do
  {foo,
end

Should be equivalent to:

def foo do
  {foo}
end

In particular, what happens in the case of mismatched do/end (additional ones or missing ones). Thanks!

So let’s go back to the previous discussion. I will move the comments there. This is about something else, which examples for are still appreciated. :)

Some tests can be found in https://github.com/elixir-lsp/elixir_sense/blob/master/test/elixir_sense/core/parser_test.exs and https://github.com/elixir-lsp/elixir_sense/blob/master/test/elixir_sense/suggestions_test.exs

This would be extremely useful. José (or anyone else), do you have any guidance on how you'd like this to be approached/implemented? I'm assuming that, for safety, we don't want to modify the existing parser, but instead introduce a completely new one. Would you start with a literal copy of the current parser and then modify it to correct/skip when issues are encountered, or do you envision a ground-up rewrite?
