Initially I thought that an option would be useful, but the complication is
that load_all() needs the path to the package files, which can be
completely different for different packages. One option would be to be
able to disable the call of library(), i.e. an option
load-library-on-developer which if true (the default) loads the package,
but if false does not load the package and leaves this to the

Yes - that works. Thanks.
But it gives the impression in R, as if it would have loaded the
package, which irritated me at the beginning, until I checked the source
code of library(), which does check if the package is already
loaded. The option verbose=TRUE in the library call might be a good
default option here.
