This may be a topic worth considering at "the upcoming Perl 5 Core Hackathon". It would be useful to have guidelines for when we should prefer to add inline functions rather than macros. I suspect we could be using them a lot more than we do, but I don't know how many platforms still have insufficient capabilities to support them. Macros suffer from lack of types on arguments, risk of multiple evaluation, and opacity in debuggers. They also do not give compilers a choice whether to inline them, so may lead to less efficient code. Inline functions cannot do everything macros can, but where they can do what is needed the only drawback I know of is that on a platform that does not support them you'll get much less efficient code.
