Code Review

correctness: 1/4edge case handling: 2/4introduced bug risk: 1/4maintainability idioms: 2/4

The patch moves toward MSSQL method-call parsing but likely does not fully satisfy the intended change due to brittle `.` infix routing and precedence-based handling, with elevated regression risk.

3 findings

Period infix handling is redirected to method parsing in MSSQL

major

In MSSQL mode, `parse_infix` dispatches `.` to `parse_method`, which expects `identifier(...)`. This broad routing can mis-handle non-method dot sequences and cause parse regressions.

src/parser/mod.rs:2883

Method support relies on precedence override hack

major

The dialect assigns `.` + `word` + `(` to `DoubleColon` precedence to force parsing, which is fragile and can alter unrelated operator behavior in hard-to-predict ways.

src/dialect/mod.rs:386

AST shape models only one method per node

minor

The new `Method` node stores a single name/args and represents chains via nesting, which is workable but less direct than a method-chain structure and complicates transformations/formatting evolution.
