Is there a good reason for this?
For some reason, the REPL can't cope with one-line blocks like that.
If you put a blank line after each one-block line then it will work.
It's actually not to do with 1-line blocks, just attempting to define 2
functions "at once":

>>> def f():

... def g():

But you are right that adding a blank line after the first function
definition solves the "problem".
