What's this?

Found an interesting [comment] in SqlDataReader's source code:

// this block of type specific shortcuts uses RyuJIT jit behaviours to achieve fast implementations of the primitive types
// RyuJIT will be able to determine at compilation time that the typeof(T)==typeof(<primitive>) options are constant
// and be able to remove all implementations which cannot be reached. this will eliminate non-specialized code for

// This script is related the following blog entry by Mark Seeman titled,
// "Builder as a monoid":
//
// https://blog.ploeh.dk/2020/02/17/builder-as-a-monoid/
//
// It demonstrates a simpler approach to avoid the ceremony of "explicit
// endomorphism" by using merely delegates. It does so by replacing
// "IEndomorphism<T>" with "Func<T, T>" and then using "+" in lieu of
// "AppendEndomorphism<T>" to achieve the same effect.
