Not really.  Using GNU Smalltalk just because it prints the result of
every statement separately, I get:

st> 0.2.3.4.5.6
0.2
3.4
5.6
st>

Braces are not a problem in this case.

I would be in favor of only accepting . as a statement separator if it
is followed by whitespace, but I would rather see other dialects do the
same.
