- fixed docs to not demonstrate reuse of built-in function
names "str" and "int", even when within a one-off script
- note: did *not* change the "str" and "int" shown in
Howto/Starting/Part1/Learning-Typeclasses.md file,
as those are class variables (i.e., Character.str and
Character.int), which does not replace the BIFs of
str() and int(). Therefore, methods inside the class
can still use the python BIFs. While this is possibly
confusing to new python programmers, it is also not
within the scope of #2549.
misc edits:
- add .vscode/ to gitignore
