Yes of course you get the spacing warning, because you have the spacing between
the print, and the braces pair. Nim is not python, just because something works
in python in a specific way it does not automatically mean that nim needs to
behave the same way. But despite that, in the current version of python you get
the same error as in Nim:
>>> print (5 + 1) * 6
6
Traceback (most recent call last):
