Mark Mitchell said so; I believe him.  I haven't used the tree inlining
compiler yet.

There are many fine examples of trivial optimisation not being done with
inline functions that are done with macros.  I assume most of them will
occur with tree inlining too (why not?).  But I will have to wait and
see.
