Ah. The issue here is that at.lineStart is a function:

- const DOLLAR_RE = createRegExp(exactly('$').at.lineStart);
+ const DOLLAR_RE = createRegExp(exactly('$').at.lineStart());

You should get a type error something like:

Argument of type '() => Input<"^\\$", never, []>' is not assignable to parameter of type 'string | Input<string, never, []>'.
