I reckon that I mix them up "with no clear reason" ... and I also reckon
that most others do, too .... but I'm not sure that my reckoning is correct
:-)

I often do:
$x = 'Hello World';
or
@stats = stat 'some.file';

but then I *always*:
print "Hello World";

Does *anyone* ever:
print 'Hello World';

??

Is there a "clear reason" for using single quotes in the assignment and the
stat(), but double quotes in the print() ?

Anyway ... my basic thinking is that you should use single quotes unless
double quotes are needed .... or unless there's some convention that
dictates the use of double quotes .... or unless you inadvertently use
double quotes in a moment of distraction :-)
