# Keep It Tight: Restrict Variadic Templates Using C++20 Concepts

**[Andreas Fertig](https://daily.dev/sources/andreasfertig)** · 2 min read · 1 upvotes · 0 comments

## Summary

Explores how C++20 Concepts can restrict variadic template parameters to a single consistent type, addressing limitations of the static_assert approach. Shows how std::same_as can enforce type homogeneity across all variadic arguments, enabling better overload support and self-documenting code compared to C++17 type trait workarounds.
