Hi,
I don't get why this produces a syntax error:
my %r = map { "a$_" => 1 } qw(q w);
yet this works:
my %r = map { "a" . $_ => 1 } qw(q w);
What is going on here?

Let me explain my goal.
Let's say I have a file with a set of paths to files:
/usr/lib32/libssl.so
/usr/lib32/libz.so
...
and so on.
What's an easy way in perl to turn that input into:
/usr/lib32/libssl.so /usr/lib32/libssl.so
/usr/lib32/libz.so /usr/lib32/libz.so
...
Basically duplicate every string to the same line, delimited by a space?
Thanks for any assistance. I use perl's regex regularly for substitutions and the like (instead of using sed) and I prefer PCRE to sed. That said, not familiar with a way to do this.
