in thread regexp word break help

I should have thought that $str and ($str) wd behave the same way.

This node explains the difference between list context and scalar context very well. Many of the replies have great links to some interesting articles on the subject.

And then why do they not perform this function in ($str) = $str =~ s/(.{1,45})\b/foo/s;, in which $str gets set to "1"?

The perlop manpage explains the return values of the m/// and s/// operators in list and scalar context. The s/// operator returns the number of substitutions in either context.
