////////////////////////////////////////////////////////////////////////
// Here we select the types that are used by default in the code base.
// The whole code base should only:
// - refer to those aliases and not use the individual scheme implementations
// - not use the schemes in a way that break genericity (e.g. using their Struct impl functions)
// - swap one of those aliases to point to another type if necessary
//
// Beware: if you change those aliases to point to another scheme implementation, you will have
// to change all four aliases to point to concrete types that work with each other. Failure to do
// so will result in a ton of compilation errors, and worse: it will not make sense!
