if we did want this to look like pure Python with the repl markers, maybe it could be:
```Python
myname
# Traceback (most recent call last):
#  File "<stdin>", line 1, in <module>
# NameError: name 'myname' is not defined
```

On the other hand, it's nice to show off the REPL... I miss having it in Dart. Maybe once browser devtools are finished :)
