That's an argument more appropriate to the 70's than now.

For a long time now, compilers have been fast enough on most
machines (perhaps not on Vaxes running VMS :-) that working
on individual modules (the most normal case), recompiling
and relinking are fast enough in most environments that this
is not a major barrier.

What is useful about fast compilers is the ability to rebuild
entire systems rapidly, which allows changes to be made to
specs with greater facility.

In the old Ada 83 days I often saw horrible kludges being
introduced in bodies to avoid changes to specs, since spec
changing was so painful for rebuilding time.
