My background is *nix, specifically SunOS/Solaris, and I had been quite happy using normal quoted strings for years. Then I installed Active Perl on a PC at home but really struggled to write one-liners because of the quoting conventions on MS Windows. When I found out about q{...} and qq{...} and applied them in one-liners they made life easy again. I have now got into the habit of using them all the time so that I don't have to make adjustments when I move between systems.

That's the only reason really. They involve a little more typing and they are not as familiar to most as quoted strings but, for me, they are more convenient.

Cheers,

JohnGG
