This change moves the Tables.jl integration functionality to a package extension to reduce precompilation time by avoiding loading heavy table-related dependencies when they are not needed. Changes: - Move Tables.jl and IteratorInterfaceExtensions.jl from deps to weakdeps - Create RecursiveArrayToolsTablesExt extension with all table traits - Remove tabletraits.jl from main module - Reduce compilation time from ~309ms to ~245ms (~20% improvement) The Tables interface remains fully functional when Tables.jl is loaded, but no longer impacts basic RecursiveArrayTools usage. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Since Tables.jl and IteratorInterfaceExtensions.jl were moved to an extension, the test files need to import them directly rather than trying to import them from RecursiveArrayTools. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Since these packages are now weak dependencies, they need to be explicitly included in the test targets to ensure the Tables functionality tests run. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
This change creates a separate extension for IteratorInterfaceExtensions.jl functionality, providing more granular control over dependency loading. Changes: - Create RecursiveArrayToolsIteratorInterfaceExtensionsExt for isiterable() - Keep getiterator() in TablesExt since it requires Tables.jl functionality - Update Project.toml to include the new extension - Avoid method conflicts by having isiterable only in the IIE extension This allows users who only need the basic iterator interface to load just IteratorInterfaceExtensions without pulling in the full Tables.jl dependency chain. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
This reverts commit e11e6a6.
The AI must have done some p-hacking..
Due to indirect dependencies, all of these packages / extensions still load all of the time (SciML/LinearSolve.jl#573 (comment)) |

Fixed by also removing the tables from Symbolic indexing interface. |
