Re: the Evil Effects of Inlining

As others have pointed out, an environment (like C++) that supports inlining
encourages the use of procedures that the programmer would manually inline in
the absence of such support. Trivial inlined procedures give you access
control to various module data, e.g. read- or increment-only access.


Another thing inlining gives you is better flow analysis with
a way to fold constants into procedures. This makes optimizations such
as
{ if (false) S1 else S2 } -> S2
more useful. In this case, you expect the body to expand to different code
in each instance.
