https://github.com/dlang/dmd/pull/8493 It's a small change, but it illustrates an important concept - separating code into functions that calculate things (which can be made pure) and functions that modify state. Doing this more generally will significantly reduce the cognitive complexity of the compiler. |

It obvious that the compilation-process is in essence a pure function mapping source_code to machine_code.
Therefore this is theoretically applicable to most of the compiler.
