The grammar contained several structural issues and ambiguities,
particularly in expression parsing, operator precedence, and the
`export` keyword. This commit restructures significant parts of the
grammar to resolve these problems and improve its formal correctness,
making it more suitable for parser generation.
The most relevant changes include:
* **Centralized Export Handling:** Corrects the definition of exports by
introducing a top-level `<declaration>` rule that distinguishes
between `<exportable_declaration>` and `<non_exportable_declaration>`.
This removes the repetitive and ambiguous `export?` prefix from
multiple individual declarations (`module`, `struct`, `fn`, etc.).
* **Unified Postfix Operations:** Integrates scoped access into the
suffix operations . This provides an unambiguous and unified
definition for these common constructs.
* **Updated Identifier Chain Issue:** Several rules in the precedence
chain ultimately resolved into starting with an identifier, this
caused ambiguitiy and issues for parsing, this was refactored in order
to correctly handle the cases.
* **Reduced Ambiguity in Statements:** Refactors complex rules like
`<variable_declaration>` and `<else_statement>` into smaller, more
explicit sub-rules (`<variable_declaration_tail>`,
`<else_statement_tail>`). This eliminates potential parsing conflicts
and improves the overall clarity of the grammar.
* **Simplified Access Expressions:** Removes the separate
`<scoped_access_expression>` and `<reflection_expression>` rules.
Their logic has been integrated directly into the more generic and
powerful postfix expression system, simplifying the grammar.
