Since this is only an issue for a developer of the package, but not for the
general user, there is no generic "reload" mechanism. What one can do is to
reload individual files with `RereadPackage` (without causing warnings about
objects already having been declared). You could simply reload the file you
worked as:
```
RereadPackage("SamplePackage","/lib/myfile.gi");
```
If your changes go over multiple files, you could put all these `RereadPackage`
commands into a single file you then read in.
One Caveat:
If you re-read a file that includes declarations, these prioperties get
re-declared, and there might be some incompatibility with objects you created
before re-reading the file.
Best,
Alexander Hulpke
