This is a story about finding a pattern by accident—and realizing, only after it worked, that it had a name. The Curiously Recurring Template Pattern, or CRTP, is a structure often associated with C++—but this isn’t a C++ article. It’s about C#, and the quiet discovery of something deeper than...
This article continues the construction of Vellum, a C# library for symbolic mathematics. If the first hundred lines laid the foundation, this next phase was about recursion: expressions within expressions, types that reproduce their own shape, and methods that evaluate themselves...
This article follows the first sessions of building Vellum, a C# library for symbolic mathematical reasoning. It begins not with features or evaluation, but with design: type systems, generics, and the quiet pleasure of getting abstractions just right.
