Or by doing something really wacky: `/(?:(*FAIL)\QThis is a comment\E)?PATTERN/` [download] Not something I recommend doing though.	[reply] [d/l]

If you want inline comments, you can use `(?# comment )` instead, which is less wacky, but I still think that it's no great thing in terms of readability.	[reply] [d/l]

Regex are tough enough to read without inserting comments into them. What's wrong with putting a detailed comment block above the regex explaining what/how it does what it does? That's what I do so when I inevitably go back to modify it at a later date, I don't have to 'learn' regex all over again.	[reply]
