I have just discovered Ruby's -w option, and I think it's really nifty.
However, I have many places in my code where I do this:

    foo       ( "this is a test"            )
    foo       ( "this is another test"      )
    foobarfoo ( "this is yet another test " )

Unfortunately, this gives me a warning:

    warning: foo (...) interpreted as method call

The problem is that I'm following my method name by a space before the
paren.  If I remove the parens or I move the paren to be next to the
method name, the warning goes away.

Why is this a warning condition?
