As pointed out, PHP and Perl differentiate.
Non-scripting languages like C, C++ and such almost always differentiate. SQL distinguishes.
Ah, Python doesn't appear to distinguish, perhaps this is how you got the idea. Python doesn't use $ to denote variables, so they don't need the distinction.

Removing the quote distinction? Posted May 19, 2005 16:07 UTC (Thu) by liljencrantz (subscriber, #28458) [Link] Actually I mostly got the idea from another language I occasionally misuse: English. It is common in written English to nest quotations within quotations by alternating between single and double quotes. It seems intuitive and useful to me, as I often end up writing strings that will be parsed at a later time. I thought that this would be unsurprising for other people as well, but it seems I might have been wrong on that one. So I may have the law of least surprise against me on this one.
On the other hand, one reason for not wanting two kinds of quotes is that I feel the constructs of computer languages should be as orthogonal as possible. This way you maximize the number of ideas that can be concicely expressed with a syntax of a given size. Two different types of quotes that do nearly the same thing does not strike me as an elegant solution.
Removing the quote distinction? Posted May 19, 2005 17:44 UTC (Thu) by smeg4brains (guest, #207) [Link] Yeah.. the language seems pretty nice, but I do have to agree with people that the quotes should be handled differently..
Maybe keep the difference in the quotes as usual, but steal python's
All of the single quote variations could skip the variable expansion, but all of the double quote versions could expand variables..
This way you can keep some of the backward compatibility with bash/sh, but you also have cleaner/better quote mechanisms as well..
Example:
echo """Hello $USER
Welcome to "Ackerman.umci.com".
echo '''To add to your $PATH variable, use something like:

I think I'll wait for a while and see if the screams for more quoting options die out. I'd rater keep the language small. Also, I'm kind of lazy.
Removing the quote distinction? Posted Mar 9, 2008 20:30 UTC (Sun) by Mysingen (guest, #50982) [Link] Why not just escape the variables instead? set a Hello set b '\$a is $a' set a Goodbye echo $b should print "$a is Hello" It is just a hassle to keep track of what will be expanded in bash scripts and I would really like the distinction between ' and " to go away.
