I've allways thought that qq() and "" where "almost" the same.
If you think that are exactly the same operator, you may be surprised (as me now)running this code:
perl -e "print qq(1_000)"

and this 
perl -e "print "1_000""

I'm now using perl, v5.6.1 built for MSWin32-x86-multi-thread Binary build 626 provided by ActiveState

Do anyone know more differences between "" and qq?
In the first, "1_000" is interpreted as a number, and in the second as a string. Why?
I've searched for documentation about this, but I didn't find nothing. 
perl -e "$_="1_000";$_++;print"
perl -e "$_=qq{1_000};$_++;print"
