@matheorem I don't remember what I tried when I wrote this. However, I tried again what happens with different options today. Assuming that "InlineExternalDefinitions" -> True, with the default "InlineCompiledFunctions" -> Automatic, small compiled functions get inlined. With False they don't get inlined. According to the docs, you need the True setting to ensure that all compiled functions will get inlined, not just small ones.

@Szabolcs Why you said "If f and g are compiled functions themselves, use the "InlineCompiledFunctions" -> True option as well."? I don't see this option is necessary. InlineExternalDefinitions is enough.

@Szabolcs Since you mentioned "InlineExternalDefinitions", you may as well mention "InlineCompiledFunctions", which is logically related (although more tangential here).

@J.M. Because in general it may have conditions on patterns, so that those definitions can not be expanded. Besides, one function may have several separate definitions with SetDelayed. In general, rule-based functions are currently non-compilable. One of the main reasons is that pattern-matcher is dynamic (data-dependent and also calls main evaluator when Condition or PatternTest are present), and so pattern-matching can not be done at compile-time, or even compiled to something efficient, without additional information which is only available at run-time. JIT might be possible though.

I do wonder why defining with SetDelayed[] doesn't work as I thought it should...
