Re: Problem w/ single-quoted strings

OK, first off, I'm a bit confused, because your first line says 'Testing\z'. Perhaps you meant 'Testing\n' ?

With that out of the way, you are missing something -- or rather, the document you just quoted is missing something.

It handles three cases:

Any character OTHER than a backslash or termination character is inserted literally. (The termination character is normally ' but may differ if q// is used.)
Any backslash followed by the termination character inserts the termination character.
Any backslash followed by a backslash inserts a backslash.

What it doesn't tell you is the fourth case:

Any backslash followed by a character OTHER than the termination character or a backslash inserts a backslash and that literal character.

The reason for the double-backslash thing is in case you wanted to include a backslash at the end of the string. For example:

$foo = 'C:\\'; # if you had 'C:\' then the ' would instead be escaped 
+instead of ending the string.
