This statement presumes that inlining is done at a near-source level
with C-like expressions, as in Cfront. Many non-Cfront compilers
allow inlining of loops. KAI's Photon C++ compiler
(http://www.kai.com/photon/photon_what_is.html) readily inlines loops.

That depends upon how many customers (that care about performance)
write inline functions with loops, and how well the rest of the
compiler optimizes loops. Now that compilers inline loops, creative
C++ programmers will no doubt find uses for inline loops.
