FIX: changes were needed to make repl example work

salexan2001 commented 1 year ago

I tried to run the example reple.rs from the examples folder. Unfortunately it did not work, but yield the following error output:

Some errors have detailed explanations: E0107, E0277.

I was able to fix the problems and make the example work again.

Most of the changes displayed in git are whitespace changes due to formatting. In fact the patch is really short and boils down to:
