Sorry to get back at you so late.

This warning is thrown for example for:

p = Proc.new {p "hallo"}
[1,2].each &p

and you don't put braces around &p.
I fixed this in 0.0.6

This perhaps misguides the user, because [] is a method call, so it do make
sense in a void context! For example aProc[params] is equivalent to aProc.call(params).
But I changed this, too.

"hallo".gsub!(...)  # no warning
"hallo".gsub! (...) # warning

same as gsub!

I redefined to_i, because I don't want to depend on the oracle.rb module,
only oracle.so. This makes sense, if we would merge someday the
C sources into DBI.

As you see, that are no errors, nothing is wrong, just hints.
But thanks anyway, I think it's better to raise as less as possible warnings
to see the "real" warnings.

Regards,
