As of semi-latest 1.9, at least, there is no warning issued, but I 
think that the results  might not be what you expect:

mark@imac% ruby -vwe'puts(0..9).to_a.join; puts (0..9).to_a.join(":")'
ruby 1.6.8 (2002-12-24) [powerpc-darwin7.0]
-e:1: warning: puts (...) interpreted as method call
0..9
0..9

mark@imac% ruby -vwe'puts(0..9).to_a.join; puts (0..9).to_a.join(":")'
ruby 1.9.0 (2004-02-21) [powerpc-darwin]
-e:1: warning: (...) interpreted as grouped expression
0..9
0:1:2:3:4:5:6:7:8:9

Apparently putting a space there was deprecated because it was marked 
for a change.
