That works!  Yay!  In particular, no complaints about a locked namespace.

However, doing C-c C-l does not work; if I modify the code and read in
the whole file, the old code seems to still be in force.

The particular way I found this out was that I inadvertently installed
the package with code that had a breakpoint in it.  When I removed the
breakpoint in the package source directory and did C-c C-l it remained
in force.  When I did C-c C-c on the function that had the breakpoint,
the breakpoint stopped firing.
