This commit addresses issue #6 by investigating how the loop modifiers (reversed, limit, offset) interact when used together. Key findings: - Go implementation: modifiers are always applied in fixed order (reversed → offset → limit) regardless of syntax order - Ruby/Shopify Liquid: syntax order matters, and reversed only works when placed before named parameters (limit/offset) Changes: - Add LOOP_SEMANTICS_INVESTIGATION.md with detailed analysis - Add test_ruby_liquid.rb for Ruby reference implementation testing - Update iteration_tags_test.go with tests for combined modifiers - Document the behavior differences from Ruby implementation The Go implementation provides more consistent and predictable behavior by using a fixed application order, though this differs from the Ruby reference implementation.
- Move test_ruby_liquid.rb to scripts/ to keep it with other utility scripts - Make script executable - Update docs/loop-semantics.md to reference the new location
