Python vs. Io

In the opinion of the creators of Io, a space looked cleaner. Using a
period looks kinda like you're finishing a sentence and starting a new
one. Consider the following syntaxes:

Dog barks //Io
Dog.barks() #Python

Regardless of which one is more common, which looks more like
language?
You say that "." is more ubiquitous, but "{}" is more ubiquitous than
":" by far, yet Python uses the latter and we don't complain. (note
that in Io, unlike other languages with similar syntax such as Ruby,
functions are first class objects.)
