# Description
Zyphys found that when parsing `{...{}, ...{}, a: 1}`, the `a:` would be
considered one token, leading to a parse error ([Discord
message](https://discord.com/channels/601130461678272522/614593951969574961/1336762075535511573)).
This PR fixes that.
What would happen is that while getting tokens, the following would
happen in a loop:
1. Get the next two tokens while treating `:` as a special character (so
we get the next field key and a colon token)
2. Get the next token while not treating `:` as a special character (so
we get the next value)
I didn't update this when I added the spread operator. With `{...{},
...{}, a: 1}`, the first two tokens would be `...{}` and `...{}`, and
the next token would be `a:`. This PR changes this loop to first get a
single token, check if it's spreading a record, and move on if so.
Alternatives considered:
- Treat `:` as a special character when getting the value too. This
would simplify the loop greatly, but would mean you can't use colons in
values.
- Merge the loop for getting tokens and the loop for parsing those
tokens. I tried this, but it complicates things if you run into a syntax
error and want to create a garbage span going to the end of the record.
