That assumption might be false. For example, you may be working on a.el, and it might have bugs. > If there is a downside, i.e. it _is_ better to > load the byte-compiled code (assuming it to be > newer than the source), what should one do? Just ignore those messages, really. They are mostly harmless. You could compile the dependent file again if you want, but that is rarely needed, mainly when they define macros that were changed, and those macros are used by the files which require a.el.
