Perl, first of all, has the 'q' and 'qq' operators. As much as I'd
come to dislike Perl after I discovered Python, I miss those two.
Every time I have to quote a string full of single/double quotes,
this comes to my mind:
q{'this' is not this, but 'that' is 'that' like 'this'}
q|'this' is not this, but 'that' is 'that' like 'this'|
q<'this' is not this, but 'that' is 'that' like 'this'>
... with 'qq' providing the version with inerpolation. I could
always find an arbitrary character for quoting that was _not_ present
in the string, and so, most of the time, avoid quoting altogether.
It was perhaps a bit too magical, but pruced very readable strings.
