Re: Single quoting weirdness

Escaping the escape character seems to be used in about any escaping mechanism that I can recall. That's hardly a Perl specific thing. And not being about to escape the delimiter is just very awkward. Do you like stuff like:

    echo '$foo'"'"'$bar'
[download]

just to be able to echo

    $foo'$bar
[download]

like you have to do in many shells?

Do I like that? Nope. But if shells were like Perl, then I could do either of the following: `echo q($foo'$bar) echo "\$foo'\$bar"` [download] and I find the former in particular to be very convenient. If there was only one quote delimiter to choose from, well that is a pain. But with the range of choices in Perl, it is pretty rare to run across a single-quote situation that wouldn't work easily. OTOH there is no syntax in Perl that gives you a row of backslashes easily. And given the way the rest of Unix works, I often want exactly that (just to pass a single backslash through several layers of interpolation - each of which loses half of them).	[reply] [d/l]
