I have a somewhat general question about the Perl concatenate operator and the append operator.

First, here is the example straight from Learning Perl (p.29)

# append a space to $str
$str  = $str . " ";

[download]
# same thing with assignment operator
$str .= " ";

[download]

My question: Are either of these method more "correct" or preferred for speed or syntactical reasons?

Any information is greatly appreciated.
