Description

According to the reference, SimplePath has always at least one SimplePathSegment.

::? SimplePathSegment (:: SimplePathSegment)*

Currently SimplePathSegment has the following attributes:

  • bool has_opening_scope_resolution
  • std::vector<SimplePathSegment> segments
  • [...]

This means the vector is never empty and is_empty always return false.

We should either:

  • Have an additional member like in QualifiedPathInExpression
  • "Fix is_empty"

Depending on the chosen approach we might also need to refactor PathInExpression.

Research direction

Start with the SimplePathSegment and PathInExpression AST definitions and compare their structure with the Rust Reference's simple-path grammar. Review QualifiedPathInExpression as the issue's example, then trace usages of is_empty and the affected nodes. Done means the representation matches the grammar and any required PathInExpression refactoring is complete.
