1. From what I've seen, looks like it depends on OS/shell. For example, it works for me when I try the same on my redhat linux/GNU bash 3.2.25.

2. However, on my windows command prompt (with ActiveState perl), I can't use single quotes for perl command line code. For example, this doesn't work - perl -e 'print "hello"', but this works perl -e "print \"hello\""

3. Moreover, is there any particular reason why you want to have double quotes as in the latter option?
